Abstract

An un-phased equal gain combining (UEGC) technique, which simply adds signals from different diversity channels, is introduced and compared with maximum ratio combining (MRC) over a satellite mobile channel (SMC). It is demonstrated that the performance with UEGC can be calculated by analyzing an equivalent SMC without diversity. Numerical results are presented for binary CPFSK signals with h = 1/2 with differential phase detection (DPD). It is numerically demonstrated that UEGC, in addition to being much simpler, performs close to MRC over channels with a higher Rician factor and/or with a higher number of diversity channels
