This paper is a study of linear phase low pass FIR filter design using different particle swarm optimization techniques (PSO). FIR filter design is basically a multi-modal optimization problem. Evolutionary algorithms like particle swarm optimization (PSO) can be used for the design of linear phase FIR low pass (LP) filter. Different improved particle swarm optimizations are proposed to address different...
Discrete cosine transform (DCT) is the most widely used transformation technique in the field of signal processing particularly in the areas of image data. This paper addresses the design of parallel architectures for computing DCT using CORDIC. It concentrates on indirect methods, which avoids decomposition of direct DCT equation. In this paper, CORDIC methodology has been used to simplify the traditional...
