Power Efficient Multichannel Discrete Time Based LTI System for DSP

Abstract

This paper proposes a power-efficient multichannel discrete-time system based on a Cat swarm-based optimization algorithm for multi-signaling processing of the different signals from different musical instruments. The purpose is to provide an adjustable signaling rate to avoid aliasing. The multichannel discrete-time system can increase and decrease the sampling frequency by fraction value according to the incoming signal's maximum frequency from various musical instrument sources. Here, the multichannel discrete-time system introduces zeros and removes the samples uniformly according to requirements. To make it power efficient and reduce resource utilization by applying particle swarm optimization algorithm at the implementation time on FPGA.
