Abstract :
We derive a formula for the bit error probability (BEP) of M-ary continuous phase frequency shift keying with differential phase detection and maximum ratio combining diversity in Rician fast-fading channels. We assume that transmitter and receiver filters distort the signal and limit the noise. We compute the BEP as a function of energy-to-noise ratio per bit (Eb/N0) and other system and channel parameters: Rician factor K=0, 6 dB, 10, ∞; number of diversity channels L=1, 2, 3; Doppler frequency shift fD T=0, 0.01, 0.02; Butterworth filters in transmitter and receiver of order NT=3 and NR=4; optimal sampling time and filter bandwidth. In all cases the BEP is significantly reduced by diversity
