摘要：

The effect of cochannel interference on the performance of digital mobile radio systems in a Nakagami fading channel is studied, The performance of maximal ratio combining (MRC) diversity is analyzed in the presence of multiple equal-power cochannel interferers and additive white Gaussian noise, Closed-form expressions are derived for the average probability of error as well as outage probability of both coherent and noncoherent (differentially coherent) binary frequency-shift keying and binary phase-shift keying schemes in an environment with cochannel interference and noise, The results are expressed in terms of the confluent hypergeometric function of the second kind, a function that can be easily evaluated numerically, The analysis assumes an arbitrary number of independent and identically distributed Nakagami interferer.
