ieee Digital signal processing workshop

作者： E. Santos M. Zoltowski School of Electrical and Computer Engineering Purdue University West Lafayette IN USA

It is well known that correlation between interferers and the signal arriving from the look-direction severely degrades the output SINR for both low-rank and full-rank minimum variance distortionless response (MVDR) beamformers. Low-rank MVDR beamformers, such as conjugate gradients (CG) and principal components inverse (PCI), can yield a higher SINR than full-rank MVDR when the sample support is inadequate. However, a large drop in output SINR occurs if the low-rank beamformer operates at an improper rank. Indirect dominant mode rejection (IDMR) is proposed wherein one first employs a high-resolution spatial spectrum estimation technique to estimate the directions and powers of the dominant interferers. Subsequently, this information is used to construct an estimate of the signal-free (interference plus noise only) autocorrelation matrix (for a given look-direction.) In this process, any correlation between the interferers and the signal arriving from the look-direction, due to either finite sample averaging or true correlation amongst signals, is effectively removed. Simulations reveal that IDMR is very robust to correlation amongst signals and yields a dramatic improvement in output SINR relative to CG and PCI/DMR, even when the latter operate at the optimal rank.

Modulo sampling and dithered one-bit quantization frame-works have emerged as promising solutions to overcome the limitations of traditional analog-to-digital converters (ADCs) and sensors. Modulo sampling, with its high-resolution approach utilizing modulo ADCs, offers an unlimited dynamic range, while dithered one-bit quantization offers cost-efficiency and reduced power consumption while operating at elevated sampling rates. Our goal is to explore the synergies between these two techniques, leveraging their unique advantages, and to apply them to non-bandlimited signals within spline spaces. One noteworthy application of these signals lies in High Dynamic Range (HDR) imaging. In this paper, we expand upon the Unlimited One-Bit (UNO) sampling framework, initially conceived for bandlimited signals as proposed in [1], to encompass non-bandlimited signals found in the context of HDR imaging. We present a novel algorithm rigorously examined for its ability to recover images from one-bit modulo samples. Additionally, we introduce a sufficient condition specifically designed for UNO sampling to properly recover non-bandlimited signals within spline spaces. Our numerical results vividly demonstrate the effectiveness of UNO sampling in the realm of HDR imaging.

The output signal components of the sensitive end of micro-electro-mechanical system (MEMS) gyroscope are complex, and the design error of the back-end demodulation circuit can greatly affect the detection accuracy of the gyroscope. Therefore, this paper designs a high-precision signal demodulation scheme applicable to MEMS gyroscope sensors. The scheme improves the traditional signal demodulation technology by combining the correlation demodulation technology and the fast Fourier transform (FFT) technology, and after the correlation demodulation of the gyroscope-sensitive signal, the infinite impulse response (IIR) filter and the FFT transform are used to jointly extract the amplitude information of the fundamental frequency signal and do the fusion processing, so as to achieve the very high precision extraction of the input angular velocity. The feasibility of the demodulation scheme is verified by field programmable gate array (FPGA) simulation. The experimental results show that the combined IIR and FFT filtering algorithm has higher demodulation accuracy than the single low-pass finite impulse response (FIR) filtering algorithm. © 2022 ieee.

Novel schemes are developed for linear dimensionality reduction of data vectors whose covariance matrix exhibits sparsity. Two types of sparsity are considered: i) sparsity in the eigenspace of the covariance matrix; or, ii) sparsity in the factors that the covariance matrix is decomposed. Different from existing alternatives, the novel dimensionality-reducing and reconstruction matrices are designed to fully exploit covariance-domain sparsity. They are obtained by solving properly formulated optimization problems using simple coordinate descent iterations. Numerical tests corroborate that the novel algorithms achieve improved reconstruction quality relative to related approaches that do not fully exploit covariance-domain sparsity.

Sparse linear arrays provide similar performance to filled linear arrays in terms of angular accuracy and resolution with reduced size, weight, power consumption, and cost. However, they are subject to significant ambiguities due to high sidelobes in the array beampattern, which give rise to large estimation errors. In this paper, we develop an explicit closed-form expression for the Ziv-Zakai bound (ZZB) on the mean square estimation error in order to quantify the degradation in estimation performance due to the sidelobe ambiguities. The bound consists of three terms which correspond to the three types of estimation errors: small mainlobe errors, errors due to sidelobe ambiguities, and random errors. The explicit bound is shown to be nearly identical to the exact numerically evaluated ZZB and to closely characterize the performance of the maximum likelihood (ML) estimator.

This paper proposes a closed-form estimation technique for a wideband constant amplitude polynomial-phase signal embedded in white Gaussian noise. It is shown that it is possible to jointly estimate the highest order phase coefficient and direction of arrivals of the signal through a closed-form method. Hence it is, computationally, much simpler than maximum likelihood method which involves highly non-linear multidimensional optimization. Simulation and comparative results are included to show its effectiveness.

We develop a novel continuous optimization algorithm to recover latent directed acyclic graphs (DAGs) from observational (and possibly heteroscedastic) data adhering to a linear structural equation model (SEM). Our starting point is the recently proposed Concomitant Linear DAG Estimation (CoLiDE) framework, which advocates minimizing a sparsity-regularized convex score function augmented with a smooth, nonconvex acyclicity penalty. While prior work focused on score function design to jointly estimate DAG structure along with exogenous noise levels, optimization aspects were left unexplored. To bridge this gap, here we show that CoLiDE has a favorable structure amenable to optimization via a block successive convex approximation (BSCA) algorithm. We derive efficient, closed-form updates to refine the DAG adjacency matrix and noise variance estimates in a cyclic fashion. Although the acyclicity regularizer is devoid of a Lipschitz gradient and hence our approximation function is not a global upper bound of the original cost, a descent direction can be obtained via line search to yield a provably convergent sequence. Numerical tests showcase the superiority of the proposed BSCA iterations relative to the original (Adam-based) inexact block coordinate descent solver.

This paper addresses the problem of spatial waveform design for collocated multiple-input multiple-output (MIMO) radar systems with sparse antenna arrays. The use of sparse arrays allows to obtain narrower beams and therefore higher angular resolution and accuracy. However, if the spatial waveform is not designed properly, the resulting transmit-receive beam-pattern may suffer from significant sidelobes or ambiguity, which can strongly degrade the estimation performance. The Bayesian Cramer-Rao bound (BCRB), which is commonly used for waveform design, may produce inappropriate results as it considers only local errors and ignores the effect of sidelobes and ambiguity. To overcome this limitation, we propose using the arbitrary test-point transformation Weiss-Weinstein bound (AT-WWB) that was recently proposed, as an optimization criterion. This bound is a simpler and tighter version of the Weiss-Weinstein bound (WWB). This bound is derived for collocated MIMO radar and is minimized with respect to the ratio between coherent and orthogonal signals. The proposed method is demonstrated via simulations, and compared to optimization schemes using the BCRB and the WWB. It is shown that the spatial waveform optimized by AT- WWB exhibits superior performance in terms of direction-of-arrival estimation accuracy.

The total energy consumed in a wireless sensor network until reaching a consensus is proportional to the product of the sum of the transmission power of each node and the convergence time. In a network where the nodes are allowed to transmit using different power levels, the minimization of this consumption is not trivial. In this paper, we propose a heuristic scheme of randomized power transmission such that the energy consumed by the network is balanced among the nodes and the convergence time is reduced with respect to a fixed symmetric topology that spends the same average transmission power. The proposed scheme establishes random links between nodes with different probabilities of connection, giving a random asymmetric topology at every iteration. Therefore, in order to minimize the convergence time of the algorithm, we use previous results on the analysis of the mean square error of the state.
