چکیده
In this paper, system performances of selection combining over correlated Nakagami-m channels are analyzed. Selection diversity based on the signal to interference ratio (SIR) is a very efficient technique that reduces fading and cochannel interference influence. Fading between the diversity branches and between interferers is correlated and Nakagami-m distributed with exponential correlation model.Very useful closedform expressions for the output SIR’s probability density function (PDF), cumulative distribution function (CDF), and outage probability are obtained, which is main contribution of this paper.

متن کاملInvestigations into Cochannel Interference in Microcellular Mobile Radio Systems
A microcell interference model termed the Nakagami m,/m, is introduced in this paper. The desired signal as well as the cochannel interferers are assumed to have Nakagami statistics but with different amounts of fading. A special case of this model is obtained when the desired signal has Nakagami statistics while the cochannel interferers are subject to Rayleigh fading. The probability density ...

In this letter, an approach to the performance analysis of a triple selection-diversity system over exponentially correlated Nakagamifading channels is presented. Closed-form expressions of converged sums for both outage and average error probabilities are derived. Numerical results are presented to point out the effect of the fading correlation, the fading severity, as well as the improvement ...
متن کاملError Rate Probability for Coded MQAM with MRC Diversity in the Presence of Cochannel Interferers over Nakagami-Fading Channels
Exact expressions for bit-error probability (BEP) for coherent square detection of uncoded and coded M-ary quadrature amplitude modulation (MQAM) using an array of antennas with maximal ratio combining (MRC) in a flat fading channel interference limited system in a Nakagami-m fading environment is derived. The analysis assumes an arbitrary number of independent and identically distributed Nakag...
