Performance Evaluation and Comparative Analysis of Various Concatenated Error Correcting Codes Using BPSK Modulation for AWGN Channel

This paper presents the performance evaluation and comparison of various concatenated error correcting codes using Binary Phase Shift Keying (BPSK) modulation scheme. Three concatenated error correcting code pair i.e. Convolutional-Hamming, Convolutional-Cyclic, Convolutional-Bose, Chaudhuri Hocquenghem is designed and the BER performance was measured for an Additive White Gaussian Noise (AWGN) channel. All pairs of concatenated codes have been compared in terms of bit error rate & energy per bit to noise power ratio and their performance reflects their error correcting capability. All simulation was done using MATLAB R2009a Simulink software. In general Convolutional-Bose Chaudhuri Hocquenghem demonstrate better performance compared to Convolutional-Hamming and Convolutional-Cyclic concatenation pairs.
