Macroscopic diversity is used to mitigate the effects of
shadowing. With macroscopic diversity, the signals received by a mobile station
(MS) from two or more geographically separated BSs are combined using usually
SC. A diversity advantage is obtained with SC if the signals experience some
degree of uncorrelated shadowing. In the uplink, signals transmitted by a MS
are received by two neighboring BSs with SNRs _1 and _2,
respectively. Since it is usually impractical to do coherent combining across
distant BSs, the BS with the largest SNR is selected to demodulate the received
signal.

mean and shadowing variance, determine the BEP for DPSK modulation and the
diversity gain at 10_3 BEP
