advanced signal-processing algorithms, architectures, and implementations

作者： Auslander, L. Buffalano, C. Orr, R. Tolimieri, R.

Effective signal detection and feature extraction in noisy environments generally depend on exploiting some knowledge of the signal. When the signal is exactly known, the matched filter is the optimum signal processing strategy. Other signal processing strategies succeed when the signal detail is but partially known. The short-time Fourier transform and the Gabor transform are two methods that exploit signal envelope information. The former is a well known and widely used representation which is important in many fields. The related but distinct Gabor transform has been less frequently used, but has features absent in Fourier analysis. This paper compares the two transforms and makes the case that the Gabor representation can often be the more compact, and may require substantially less computation and storage in some applications. There is a sense in which the Gabor achieves a preferential trade of signal-to-noise ratio for resolution, and because of this, one can also expect better signal recognition and feature reconstructions from the Gabor transform in the presence of noise.

advanced signal processing: algorithms, architectures, and implementations V

作者： Swami, Ananthram Rao, Preeti CS-3 Los Angeles CA USA

ISBN: (纸本)0819416207

Interactions among spontaneous otoacoustic emissions (SOEs), which are narrow-band signals emitted by the cochlea, include the cubic difference tone (CDT) that occurs at frequency 2f 1 - f2 due to the nonlinear coupling of primary SOEs at f1 and f2. We show that appropriately defined trispectra and tricoherence may be used to detect the CDTs. OAE signals are also characterized by temporal variations in the amplitudes and frequencies;this leads to polynomial phase models, and multiplicative noise processes;we give closed-form expressions for the large sample CRLB for the parameters of the resulting model. We also consider cyclic approaches, and we compare polyperiodogram and periodogram based approaches for the detection of arbitrary frequency coupling laws. Some of the techniques are validated against real data.

ISBN: (纸本)0818662751

In this paper, we present efficient parallel solutions for structural indexing-based object recognition on coarse-grained parallel machines. Based on the analysis using the C3-model, the parallel algorithm proposed in this paper takes O(Sk/p) computation units and O(p3,2) communication units on a p processor coarse-grained machine such that 1 ≤ p ≤ S, whereas the sequential solution takes O(Sk). The proposed solution is implemented on the Intel Touchstone Delta and performance results are shown. For a scene consisting of 160 feature points, the recognition phase takes 258 ms on a 64 processor Delta when the model database contains 256 models. The sequential algorithm takes approximately 4 seconds on a single node of the Delta. © 1994 IEEE.

Time frequency filtering and synthesis from convex projections

advanced signal-processing algorithms, architectures, and implementations

作者： White, Langford B. Defence Science and Technology Organisation Salisbury Australia

This paper describes the application of the theory of projections onto convex sets to time-frequency filtering and synthesis problems. We show that the class of Wigner-Ville Distributions (WVD) of L2 signals form the boundary of a closed convex subset of L2(R2). This result is obtained by considering the convex set of states on the Heisenberg group, of which the ambiguity functions form the extreme points. The form of the projection onto the set of WVDs is deduced. Various linear and non-linear filtering operations are incorporated by formulation as convex projections. An example algorithm for simultaneous time-frequency filtering and synthesis is suggested.

学位级别：博士

Over the past few years FPGA hardware has become a logical choice for imple- menting cutting-edge signal processing applications. While there have been advances in FPGA technology, the common process of creating specialized hardware imple- mentations for them is a manual one involving extensive design exploration. Design exploration is a process that requires a designer to look for designs that t a set of performance characteristics such as size, throughput, or power depending on the application and it can be the most time consuming step when creating FPGA hard- ware. This process is a nontrivial task that requires extensive background knowledge of both FPGA hardware and the application being implemented. While advances have been made in automating the process of design, there is still a gap between the application writers and hardware engineers that can be lled. This thesis presents a novel approach for automating the generation of hardware design search spaces that contain a comprehensive set of ways to implement signal processing algorithms with FPGAs. To accomplish this we generate a set of equiv- alent mathematical representations for an input equation via a novel declarative programming language that avoids a number of diculties associated with the im- perative languages used by previous approaches. We show that this equation space is bounded in terms of bracketing and ordering of mathematical operations, and that by changing the way an equation is written we can generate unique hardware instantiations (designs). The generated instantiations are mapped to heterogeneous computing architectures and written in a structural hardware descriptive language style to ensure that the intended instantiation will behave as predicted in hardware. A software system was created based on this approach that generates an equation space for varying numbers of summed multiplications and converts each representa- tion into a comprehensive hardware design search space that can be a

Dynamically Reconfigurable architectures for Real-time Baseband processing

Dynamically Reconfigurable Architectures for Real-time Baseb...

作者： Chenxin Zhang University of Lund

学位级别：博士

Motivated by challenges from today's fast-evolving wireless communication standards and soaring silicon design cost, it is important to design a flexible hardware platform that can be dynamically reconfigured to adapt to current operating scenarios, provide seamless handover between different communi- cation networks, and extend the longevity of advanced systems. Moreover, increasingly sophisticated baseband processing algorithms pose stringent re- quirements of real-time processing for hardware implementations, especially for power-budget limited mobile terminals. With existing hardware platforms such as Application-Specific Integrated Circuits (ASICs), Field-Programmable Gate Arrays (FPGAs), and Digital signal Processors (DSPs), the contradictory design requirements of flexibility, computational performance, and hardware ef- ficiency cannot be attained at the same time. To achieve a balance between the aforementioned design requirements, a coarse-grained dynamically reconfigurable cell array architecture is proposed. The architecture is constructed from an array of heterogeneous function units interconnected through a hierarchical on-chip network. The adopted in-cell configuration scheme enables fast context switching between standards and be- tween computational tasks during run-time. Although cell array is a generic hardware platform, this thesis focuses on the architectural development of the cell array tailored specifically for digital baseband processing of contemporary wireless communication systems. Various degrees of flexibilities among operat- ing scenarios, algorithms, tasks, and supporting standards are exploited. Be- sides, high hardware efficiency is attained by conducting algorithm-architecture, hardware-software, and processing-memory co-design. In this thesis, flexibility, performance and efficiency of the proposed archi- tecture are demonstrated through two case studies. First, the cell array is de- ployed in a digital front-end receiver, aiming t

Advance signal processing algorithms, Atchitectures, and implementations X

作者： Groutage, Dale Bennink, David Naval Surface Warfare Cent Bremerton United States

We present a matrix decomposition that can be used to derive features from processes that are described by discrete-time, time-frequency representations. These include, among others, electrocardiograms, brain wave signals, seismic signals, vibration and shock signals, speech signals for voice recognition, and acoustic transient signals. The new decomposition is based on a transformation of the basis vectors of the singular value decomposition (SVD) which we call transformed singular value decomposition or TSVD. The transformed basis vectors are obtained by forming linear combinations of the original SVD basis vectors in a way such that the means of the transformed vectors are extrema of each other. The TSVD basis vectors are used to identify concentrations of energy density in the discrete-time, time-frequency representation by time and frequency descriptors. That is, descriptors such as the location in time, the spread in time, the location in frequency and the spread in frequency for each principal concentration of energy density can be obtained from the TSVD terms in the matrix decomposition series. Several examples are presented which illustrate the application of the new matrix decomposition for deriving principal time and frequency features from the discrete-time, time-frequency representations of nonstationary processes. Two of the examples illustrate how the derived time and frequency features can be used to classify individual short duration transient signals into respective classes, that is,: (1) automatically classify sonar signals as belonging to one of ten classes, and (2) automatically classify heartbeat signals as belonging to one of two people.

Proceedings of the 1999 advanced signal processing algorithms, architectures, and implementations IX

作者： Xu, Gang Cavallaro, Joseph R. Rice Univ Houston United States

The multistage detection algorithm has been widely accepted as an effective interference cancellation scheme for next generation Wideband Code Division Multiple Access (W-CDMA) base stations. In this paper, we propose a real-time implementation of this detection algorithm in the uplink system, where we have achieved both high performance in the interference cancellation and computational efficiency. When interference cancellation converges, the difference of the detection vectors between two consecutive stages is mostly zero. We recode the estimation bits, mapping from ±1 to 0 and ±2. Bypassing all the zero terms saves computations. Multiplication by ±2 can be easily implemented in hardware as arithmetic shifts. The system delay of a three-stage detector can be reduced by half with satisfactory bit error rate. We also propose a VLSI implementation of this algorithm that has the potential of real-time performance. The detector handling up to eight users with 12-bit fixed point precision was fabricated using a 1.2 μm CMOS technology.
