Sampling-Based Estimation of DQPSK ...

A general Monte Carlo estimator for calculation of bit error rates for a class of noncoherent and differentially coherent communication systems is introduced. This estimator, by exploiting the connection between the Generalised Marcum Q-Function and Poisson distributions, is applied to the case of differential quadrature phased-shift keying over a frequency-selective Nakagami-m channel with an arbitrary power delay profile. It is confirmed that this estimator is efficient, and provides good results in practice.
