In this paper, we analyze the error performance of coherent M-ary FSK (MFSK) signals using the union bound which is an upper bound on the bit error probability over frequency-nonselective slow Nakagami and Rician fading channels with additive white Gaussian noise (AWGN), respectively. Furthermore, the performances of uncoded coherent and noncoherent signals are compared under the fading channels. The error probability of noncoherent MFSK signals over slow and flat fading channels when AWGN is present can be derived and evaluated from the new probability density function (PDF) for the envelope of the received signals.
