Comparison of the performance of DCSK for PLCC with and without data compression

Abstract

Differential Code Shift Keying (DCSK) communication scheme a modified version of spread spectrum technology meant for power line carrier communication (PLCC). In power line conditions, this modulation scheme has its own advantages over other conventional modulation techniques. Development of DCSK scheme in MATLAB environment to transmit character string suffers with longer superchirp length particularly for increased string length. This problem is eliminated by compressing the data string by employing Basic Arithmetic Coding and Huffman Coding based compression before transferring the information employing DCSK. In this paper, the performances for all the developed algorithms are compared to determine the advantages and drawbacks of algorithms.
