In this paper we obtain a Maximum Likelihood Estimator (MLE) for average received power in a multiuser non coherent multiple frequency-shift keying (MFSK) system over a fast Rayleigh fading channel. It is shown that this estimator is unbiased and that its variance can be obtained by a simple linear function. The Cramer Rao lower bound (CRLB) is derived and compared to the MLE's variance. It is shown that in most of the practical cases the MLE is inefficient by a multiplier that depends on system parameters but not on the number of sample points used. Numerical results are obtained and average performance is analyzed. (AU) | |
