Adaptation is a primary issue for achieving efficient bandwidth utilization in wireless communication systems because of dynamic fluctuations in channel conditions. This paper details the implementation of an adaptive channel coding and modulation system using Reed Solomon (RS) codes. RS codes are non-binary error correcting codes that are capable of correcting burst and random errors. This paper investigates the effects of an Additive White Gaussian Noise (AWGN) channel on the performance of RS coding methods for different errors correction capability. Relation among BER for different code rates and the performance of RS codes for various modulation schemes is analysed. Based on the obtained analytical results, an adaptive channel coding scheme is designed. Simulation and analysis of the proposed system is done on MATLAB with real time implementation on TMS320C6713 digital signal processing (DSP) Kit.
