Description: The error probability analysis of a Differential Phase Shift Keyed (DPSK) receiver employing diversity combining techniquesis performed. It is assumed that the system operates over a frequency non-selective, slowly fading Rician channel. This thesisanalyzes Equal Gain Combining (EGC), Selection Combining (SC) and Post Detection SelectionCombining (PDSC). The first two diversity combining techniquesare widely used in communication systems, while Post Detection Selection Combining is a new technique. Previous analysis of the EGC and the SC techniques shows that the EGC technique has a better performance than the SC technique in a Rayleigh fadingchannel. In this thesis, the effecton the performance of a noncoherent DPSK receiver using the diversity combiningtechniques for Rician fading is examined. It is shown that the PDSC technique provides a performance that is better than the SC but worse than the EGC technique. The PDSC technique allows a relatively simple receiver structure independent of the number of diversity branches.
