Performance evaluation of phase shift keying modulation technique using BCH code, Cyclic code and Hamming code through AWGN channel model in communication system

Abstract

This paper presents the performance evaluation of phase shift keying technique modulation such as BPSK and QPSK using error correcting code. Three error correcting codes types; Bose-Chaudhuri-Hocquenghem (BCH) code, Cyclic code and Hamming code were used as the encoder/decoder technique to calculate the bit error rate through an Additive White Gaussian Noise (AWGN) channel. Basically, the performance was determined in term of bit rate error (BER) and signal energy to noise power density ratio (Eb/No). Both BPSK and QPSK were also being compared in the symbol error capability known as t in which expected that the performance is graded in response to the increasing of value of t. All simulations were done using MATLAB R2007b software. In general BCH codes demonstrate best performance than Hamming code and Cyclic code for both BPSK and QPSK.
