چکیده

A Doppler filter bank (DFB) is the heart of pulsed Doppler radar and gives clutter filtering and coherent integration. With these capabilities, it provides the improvement of detection probability as well as velocity discrimination, which can detect small targets in clutter environment. This paper implements a DFB with parallel processing configuration using multiple digital signal processors (DSPs). By analyzing distribution time of the input data, computation time of the algorithm, transfer time of the output data and the ratio of computation time to total processing time, it is shown that the general timing diagram for parallel processing can be applied to the implemented DFB.

Filtering of Volume Clutter in Pulse Surveillance Radar using Discrete Wavelet Transform

Moving weather systems will have a nonzero Doppler response at rate at which the rain droplets are approaching the radar system. The complete data the radar collects contain the returns of both the target and the clutter. The signal processing block in a radar system uses filtering operations to extract the target information while suppressing the clutter. Typically the filters are designed bas...

On the Use of Filter Banks for Parallel Digital Signal Processing

Abstract – In parallel processing of digital signals, we require an algorithm which can be “parallelized” to take advantage of multiple processing units or a signal decomposition whereby each component in the signal decomposition can be processed in parallel. The filter bank is introduced as one way to provide a signal decomposition useful in parallel signal processing. In this paper, we review...

An Oversampled Filter Bank Approach to Independent Component Analysis for Convolved Mixtures

We present a new approach to perform independent component analysis (ICA) for convolved mixtures. This approach is based on filter banks, and its decimation provides much less computational complexity and faster convergence speed than the time domain approach. In addition, the approach does not have a performance limitation unlike the frequency domain approach. One can select the number of filt...

Sensitivity analysis of offset QAM multicarrier systems to residual carrier frequency and timing offsets

This paper presents a sensitivity analysis of filter bank multicarrier (FBMC) systems to carrier frequency offset (CFO) and timing offset. Although the emphasis of the paper is on the class of FBMC systems that are based on offset quadrature amplitude modulation (OQAM), the developed results are found applicable to cosine modulated-based FBMC systems as well. We assume that coarse CFO and timin...

A New Method to Improve Automated Classification of Heart Sound Signals: Filter Bank Learning in Convolutional Neural Networks

Introduction: Recent studies have acknowledged the potential of convolutional neural networks (CNNs) in distinguishing healthy and morbid samples by using heart sound analyses. Unfortunately the performance of CNNs is highly dependent on the filtering procedure which is applied to signal in their convolutional layer. The present study aimed to address this problem by a...
