Performance analysis of BPSK and QPSK using error correcting code through AWGN

Abstract

This paper highlight the performance analysis of BPSK and QPSK using error correcting code. To calculate the bit error rate, different types of error correcting code were used through an Additive White Gaussian Noise (AWGN) channel. Bose-Chaudhuri-Hocquenghem (BCH), Cyclic code and hamming code were used as the encoder/decoder technique. 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 better performance than Hamming code and Cyclic code for both BPSK and QPSK.
