Abstract-We derive an infinite seriesexpressionof the average
signal-to-noise ratio (SNR) gain for a dual selection combining
system under Nakagamiln fading using a series representation
of the bivariatecumulative probability distributionfunction.The
averageS N R gain expression is shown to relate to the Nakagami
shape factor m, the power correlation and the power allocation
ratio.
1. INTRODUCTION
HE use ofmulti-element antennas can increase the perfor-
Tmance of wireless systems by utilising spatial diversity.
By assuming independence between the received signals from
various antennas, the performance of common multi-element
antennas systems, such as maximal ratio combining, equal gain
combining and selection combining, have been reported [1,2].
