Abstract

Closed-form solutions for the average error rate of MDPSK, coherent MPSK, and noncoherent MFSK over slow, flat, Rician fading are derived. The solutions are sufficiently simple so that no approximations are needed for the numerical computations and general enough so that it includes AWGN and Rayleigh fading as special cases. Error probabilities are graphically displayed for various values of M. The dependence of error rate on the channel specular-to-scatter ratio are plotted and examined. Performance comparisons for a range of values of the Rician parameter K, corresponding to the measured statistics of mobile and indoor wireless channels, are made for the different digital modulation schemes. The analytical results presented in this paper are expected to provide information that is important for radio systems design and the evaluation of performance over a fading channel
