Abstract :
This paper introduces two general relationships concerning the output signal-to-noise ratio distribution and the bit error performance of the nonideal maximal ratio combiner. The imperfections are modeled as Gaussian distributed weighting errors in the channel gain estimates used for coherent combination. The general form for the bit error rate is applicable to any modulation format
