RESUMO

Diversity combining is an important technique usually employed to alleviate the unwanted efects of the cochannel interference. Equal-gain and maximal-ratio combining are considered here, as they are two of the most important space diversity methods. Unfortunately, the evaluation of the multifold nested integrals required in the exact outage probability analysis of such systems is not computationally feasible. In order to out°ank the complexity of this task, we present a simple approximate method. In the proposed model, the system is composed of M diversity branches and N arbitrary independent cochannel interferers undergoing generalized fading channels, namely a-µ, k-µ and n-µ. The approximate formulations are compared against Monte Carlo simulation results and an excellent agreement between them is achieved
