Besides the hardware complexity and hence increased power consumption, M-ary modulation schemes ensure improved performance and bandwidth efficiency. But, in wireless sensor networks where power consumption is a critical issue, it is required to consider non-coherent M-ary schemes together with the possible ways of improving their performance. This paper is a study of BER performance of Reed-Solomon Coded M-ary frequency shift keying (MFSK) under AWGN, multipath Rayleigh and Rician fading channels. Simulations were run using Matlab/Simulink model. The simulation results show that, Binary input RS Encoder-Decoder provides improved BER when compared to that of Integer input RS Encoder-Decoder, especially for the preferred smaller values of M.
