Abstract-- New Results for the performance analysis of maxi-
mal ratio combining (MRC) using BPSK modulation in spatially
correlated Rayleigh fading channels with imperfect channel
knowledge are presented in terms of antenna array configu-
ration and parameters of scatterer distributions. The utility
of recently developed expressions for bit error probability is
enhanced by application of a spatial correlation formulation for
arbitrarily spaced antennas and general scatterer distributions.
The results of performance analysis give valuable insight into
the performance of MRC in realistic Rayleigh fading scenarios
