Since the optimal detector for coded and even uncoded multiple-input-multiple-output (MIMO) antenna systems results too complex when the number of antennas and/or the modulation order index increases, strictly low-complexity detection schemes are considered, aiming to achieve promising performance times complexity trade-off. Under the same throughput basis, this work analyzes some capacity-approaching heuristic and reduced tree-search MIMO detection algorithms, combining simple linear decouplers, local search detectors, particle swarm intelligence (PSO) concepts and parallel short low density parity check codes (LDPC), suitable to uncoded as well to MIMO channel coding. For uncoded MIMO systems, low-complexity PSO approach showed to reach efficiently MIMO near-capacity for any number of transmit and receive antennas configuration, while simple linear decoupler detectors for QPSK modulation with short LDPC coding achieve reasonable performance only for n R ges n T condition.

Intelligent Sensors, Sensor Networks and Information Processing Conference (ISSNIP)

作者： Yongan Wu Jianping Yin Min Li Zhu En Zheng Xie School of Computer Science National University of Defense Technology Changsha China College of Science National University of Defense Technology Changsha China

The fundamental issue in sensor networks is the quality of monitoring provided by the networks under the energy constraint. The quality is usually measured by coverage. In this paper, unlike previous research, the k-coverage problem is investigated in the directional sensor networks with turnable orientation. Furthermore, probabilistic sensing model is adopted for more realistic than deterministic model. Because the problem is NP-hard, two approximate algorithms, centralized Inter Linear Programming Algorithm (ILPA) and distributed Coverage Benefit detection Algorithm (CBDA), are proposed. By modelling the problem as an ILP problem, ILPA loosens the integer constraint and converts the optimal LP solution to a feasible ILP solution with a proven approximation guarantee. As a distributed algorithm, CBDA utilizes a back-off timer to decide active sensors and their direction with large coverage benefit. It is proved that the solutions gotten by ILPA and CBDA are feasible. And the time complexity, the communication complexity and the performance ratio are theoretically analyzed. Compared with the best known existing coverage algorithm in directional sensor networks [13], simulation results show that ILPA and CBDA significantly reduce the percentage of active sensors and prolong the network lifetime in some sense.

An investigation of state-space model fidelity for SSME data

An investigation of state-space model fidelity for SSME data

引用

International Conference on Prognostics and Health Management, PHM

作者： Rodney A. Martin NASA Ames Research Center CA USA

In previous studies, a variety of unsupervised anomaly detection techniques for anomaly detection were applied to SSME (space shuttle main engine) data. The observed results indicated that the identification of certain anomalies were specific to the algorithmic method under consideration. This is the reason why one of the follow-on goals of these previous investigations was to build an architecture to support the best capabilities of all algorithms. We appeal to that goal here by investigating a cascade, serial architecture for the best performing and most suitable candidates from previous studies. As a precursor to a formal ROC (receiver operating characteristic) curve analysis for validation of resulting anomaly detection algorithms, our primary focus here is to investigate the model fidelity as measured by variants of the AIC (akaike information criterion) for state-space based models. We show that placing constraints on a state-space model during or after the training of the model introduces a modest level of suboptimality. Furthermore, we compare the fidelity of all candidate models including those embodying the cascade, serial architecture. We make recommendations on the most suitable candidates for application to subsequent anomaly detection studies as measured by AIC-based criteria.

Euromicro Symposium on Digital System Design

作者： Francisco J. Jaime Javier Hormigo Julio Villalba Emilio L. Zapata Department Computer Architecture University of Malaga Spain

The Hough transform is a line detection algorithm widely used within image processing applications, showing several variations depending on the shape which is intended to be detected. This paper provides for some new SIMD instructions aided by a specialized look-up table specifically devised for an improved Hough transform algorithm implementation, although they may also be used within other algorithms implementation with a slight modification. The new approach has been tested and evaluated using SimpleScalar tool set.

IEEE International Conference on Communications (ICC)

作者： H. Wang Y. Chang Wireless Theories and Technologies Laboratory (WT&T) Beijing University of Posts and Telecommunications Beijing China

In the conventional zero-forcing successive interference cancellation (ZF-SIC) detection algorithm of vertical Bell-Labs layered space-time (V-BLAST) architecture, the detection algorithm does not attempt to eliminate the effect of the error propagation, which is significantly deleterious to hybrid automatic repeat request (H-ARQ) scheme using bit-level Chase combining. Based on two ordering approaches respectively, we propose two novel H-ARQ bit-level Chase combining algorithms in this paper, which employ a new log-likelihood ratio (LLR) calculation algorithm to minimize the effect of the error propagation. Through simulation results, it is shown that the new proposed algorithms outperform the conventional ones on system performance and these proposed approaches are also applicable in corresponding MMSE algorithms.

Wireless sensor networks have many potential applications for both civil and military tasks. However, WSNs are susceptible to many types of attacks because they are deployed in open and unprotected environment. Selective forwarding attack is one of the easiest implement and damaged attacks in multi-hop routing protocols. In this paper, we proposed a lightweight detection algorithm based only on the neighborhood information. Our detection algorithm can detect selective forwarding attack with high accuracy and little overhead imposed on detection modules than previous works.

IEEE Conference on Vehicular Technology (VTC)

作者： Hufei Zhu Wen Chen Dageng Chen Yinggang Du Jianmin Lu Wireless Research Department Huawei Technologies Company Limited China Department of Electronic Engineering Shanghai Jiaotong university China

We propose a fast algorithm to compute an initial triangular square-root of the estimation error covariance matrix for BLAST, which are then applied to develop a square-root algorithm for BLAST. The speedups of our square-root BLAST algorithm over the previous square-root BLAST algorithm in the number of multiplications and additions are 3.78-5.8 and 3.95-5 respectively, and the ratios between the computational complexity of our BLAST algorithm and that of the linear MMSE detection algorithm in the number of multiplications and additions are 1.10-0.71 and 0.90-0.71 respectively, which means that for the first time, the nonlinear MMSE BLAST detector with successive interference cancellation can have even lower complexity than the linear MMSE detector. Moreover, our BLAST algorithm is also numerically stable and hardware friendly, since it uses unitary transformations to avoid the matrix inversions, and gets the initial square-root which is equivalent to a Cholesky factor of the estimation error covariance matrix.

Caption detection in the video is an active research topic in recent years. In the conventional methods, one of most difficult problems is to effectively and quickly extract the durations of the different-size captions in the complex background. To solve this problem, a novel and effective method is presented to locate and track the captions in the video. The main contributions are: (1)present a multi-scale Harris-corner based method to detect the initial position of the caption (2)propose the SGF (Steady Global Feature) to determine the caption duration. Extensive experiments demonstrate the effectiveness of the proposed method.

Wireless sensor networks have been receiving an increasing interest in the field of structural health monitoring to provide rich sets of real-time information of complex structures. Due to the bandwidth and power limitation of wireless sensor networks, distributed data processing, damage detection, and decision making are appropriate for the development of wireless structural health monitoring systems, which requires wireless sensor units equipped with data processing and damaged detection algorithms. This paper proposes an open software architecture design approach for the implementation of structural health monitoring algorithms in wireless sensor nodes. The open software architecture design approach promotes software reuse and welcomes the contributions from research communities.

An efficient single pass approach to frequent episode discovery in sequence data

引用

2008 IET 4th International Conference on Intelligent Environments

作者： Sagar Savla Sharma Chakravarthy IT Laboratory & Department of Computer Science and Engineering University of Texas Arlington Arlington TX USA

There is a considerable body of work on sequence mining of transactional data. Most of the related work on point data make several passes over the entire dataset in order to discover frequently occurring episodes/patterns. The OnePass frequent episode discovery (or FED) algorithm, proposed in this paper, takes a different approach than the traditional apriori class of pattern detection algorithms. In our approach, significant intervals for each event (or device) are computed first (independently) and are used for detecting frequent patterns along with the interval in which they occur. The advantage of this approach is that the data set is compressed substantially in the first step thereby reducing the size of input used and hence the computation. Also, each event/device can be processed individually allowing for parallel computation of individual events. The OnePass FED algorithm then works on these significant intervals to discover interesting episodes in a single pass as compared to the apriori class of algorithms. Our approach is significantly more efficient and scales as well as compared to traditional mining algorithms. Extensive experimental analysis establishes its efficiency and scalability.
