The classification of electroencephalographic (EEG) signals is an important issue in the ongoing research of brain-computer interface (BCI) technology. One such BCI uses slow cortical potential measures to infer user intent from the original brain activity. In the paper seven features based on the standard low-level signal properties are evaluated in their ability to classify brain activities, and thus make up for the scarcity of signal features for the current EEG signal categorization. In addition, a paradigm is proposed to select effective low-level features for EEG signal classification. Combining the features selected by the paradigm with the DC value of slow cortical potentials for categorization based on a Bayesian classifier, we obtained significant improvement on classification accuracy for data set Ia of BCI competition 2003, which is a typical representative of one kind of BCI data. © 2005 ieee.

For airborne synthetic aperture radar (SAR) without precise measuring systems, signal-processing method can play an important role in motion compensation system. The main ideal is to extract all the necessary motions or Doppler parameters of the aircraft by evaluating the azimuth spectra of the radar raw data. The reflectivity displacement method (RDM) algorithm is described in this paper, and tested with the actual experimental data.

Increasing demand for automatic large area surveillance has made methods estimating direction of arrival (DOA), especially acoustic methods, an interesting topic. In these systems false alarms and faults are a disturbing factor. This paper presents a reliability criterion and a new method to diminish these errors. In very low signal-to-noise ratio conditions there are seldom any means to improve the performance of a DOA estimator. In these cases it is important to have some information about the estimation reliability. Our focus is on wideband signals propagating as planar waves in three dimensional space. If the estimation method makes no assumptions on the signal propagation speed, it is possible to compute a reliability measure for obtained estimates. With this reliability measure we are able to decide whether the data produced by a time delay based DOA estimation system is usable or not. Indeed, with this criterion an estimation system can state its own reliability.

Towards real time implementation of reconstructive signal processing algorithms using systolic arrays coprocessors

引用

JOURNAL OF systems ARCHITECTURE 2010年第8期56卷 327-339页

Reconstructive signal processing algorithms encompass a broad spectrum of computational methods. Fortunately, most of the methods fall into the classes of the matrix algebraic calculations, convolution, or transform type algorithms. These algorithms possess common properties such as regularity, locality and recursiveness. Considering such general class of reconstructive signal processing (SP) techniques, in this paper we propose a new Hardware/Software (HW/SW) co-design paradigm for the implementation of reconstructive SP algorithms via efficient systolic arrays integrated as digital SP coprocessors units. In particular, the selected matrix-matrix and matrix-vector multiplication algorithms are implemented in a systolic computing fashion that meets the real time SP system requirements when employing the developed Hardware/Software Co-Design method oriented at the use of a Xilinx Field Programmable Gate Array (FPGA) XC4VSX35-10ff668.

Soccer robot games are rapidly becoming a major research tool in field of AI, machine vision and motion control. The dynamism of the environment in the size of state space makes such a design challenging. In this paper we develop optimal reactive strategies for the game using groundtruth data from experts, with potential fields as base of the strategies. Experiment shows that the strategy has good active characteristics and can satisfy the game demand.
