A. Abdi et M. Kaveh, Comparison of DPSK and MSK bit error rates for K and Rayleigh-lognormal fading distributions, IEEE COMM L, 4(4), 2000, pp. 122-124
The composite Rayleigh-lognormal distribution is mathematically intractable
for the analytical evaluation of such a communication system performance m
etric as bit error rate. The composite K distribution closely approximates
the Rayleigh-lognormal and-is potentially useful for analytical manipulatio
ns. In this contribution we derive the bit error rates of differential phas
e-shift keying (DPSK) and minimum shift keying (MSK), in, manageable closed
forms, for the K distribution model of multipath fading and shadow fading,
and show, numerically, the close agreement between these results and those
based on the Rayleigh-lognormal distribution.
