Abstract

Outage probability for maximal ratio combining (MRC) is usually tackled in the framework of Rayleigh or Nakagami faded co-channel interferers with equal power, which allows for the treatment of the total interference power as a single gamma distributed variable to simplify the analysis. The more general case with unequal-power co-channel interferers is formulated and solved differently in this paper ending up with simple closed-form solutions for Rician/Rayleigh and Nakagami/Rayleigh channel models.
