Reed-Solomon Code Performance for GMSK Modulation over AWGN Channel

The main objective of this paper is to find the performance of Reed-Solomon code for Guassian Minimum Shift Keying (GMSK) modulation overa Additive White Guassian Noise (AWGN) channel. The simulation model provides error detection and correction using Reed-Solomon (RS) Codes. The Original message is encoded and decoded using RSCodes.MATLAB simulation is selected as the investigating tool.Theperformance of proposed GMSK and RS code combination simulation is compared with uncoded system with the constraint that the transmission bandwidth is constant.Wealsoperformed the simulations for different code rates and different block lengths with fixed number of error. The results are presented by a plot between the bit errorrates (BER) and signal to noise ratio using Monte Carlo simulation.Theresultsshowthatforagiven bandwidth, it is beneficial to use a smaller coderate but only to a certain value otherwise the system performance deteoriates. The BERperformance also improves by decreasing code rate and by taking large block lengths or by increasing redundancy.
