M-CPM with MRC diversity in Rician-, Hoyt-, and Nakagami-fading channels

An equation is derived for the bit error probability (BEP) of M-ary continuous phase modulation (CPM) with differential phase detection (DPD) and maximal ratio combining (MRC) in various fading channels. As an example, the BEP of Gaussian minimum shift keying with B/sub g/T=0.5 is computed. In the case of a Rician channel, the Doppler frequency shift is also taken into account. As an example, the BEP of M-ary continuous phase frequency shift keying with M=2, 4, 8 and f/sub Dm/T=0.04 is computed.
