Abstract—The performance ofmaximal ratiocombining for
space diversity reception in digital cellular mobile radio systems is
studied for communications in the presence of multiple cochannel
interference(CCI)sourcesandiscomparedtooptimumcom-
bining. The main contribution of the paper is that the analysis
accountsforfadingofthesignalofinterest(SOI)aswellas
thecochannelinterference(CCI).ThepaperconsidersBPSK
signalling in flat, quasi-static channels. Rayleigh or Rice fading is
assumed for the SOI, while CCI is assumed subject to Rayleigh
fading. Channels associated with interference sources are assumed
independentandidenticallydistributed.Usingamultivariate
statistical analysis approach and assuming equal-power interfer-
ence sources,analytical expressions are derived for the density
function of the array output signal-to-interference ratio (SIR), the
outage probability, and the average probability of bit error with
maximal ratio combining. Earlier results obtained for optimum
combining and Rayleigh fading are extended to the case when the
SOI is subject to Rice fading. A limited analysis of the equal gain
combiner is also presented.
