| Abstract: | A bit-error probability formula for Gaussian minimum-shift keying (GMSK) satellite mobile communication system with differential phase detection(DPD) and L-branch maximal ratio combining(MRC) under different channel conditions was presented. The numerical results based on the field testing data were also given. |
