Performance analysis of concatenated codes for different channels
N K Sharanya, Srivatsa Ramesh Jayashree · 2016
Forward Error Correction codes are required to remove errors such as noise, crosstalk etc that transpire in communication channel. In this paper, we propose a concatenated (Single Parity Check, BCH and Low Density Parity Check) coding method to remove the errors and improve the efficiency of the system. Simulation results shows that Single Parity Check method along with BCH and Low Density Parity Check gives better results. Performance of these coding methods in different channels such as AWGN, Rayleigh and Rician channels are also simulated. SPC method having simple encoding and decoding mechanism does not give good BER. LDPC in contrast to BCH achieves higher performance and better error correction capability.
