Abstract: Single and multi-user performance of the spread-spectrum modulation technique called differential frequency hopping (DFH) and its performance comparison against fast frequency hopping (FFH) multiple-access system are the main focuses of this dissertation, Dl-H and FFI I are compared based on the assumption of equal bandwidth. Under the absence of noise and fading, we study how multi-user interference (MUI) influences the performance of a multiple access OFH system. The concepts of singleuser and multi-user efficiency have also been included in the discussion which can be considered as a reasonable means to compare FFI I and OFII systems. For the same bits per symbol and same dwell time, it is shown that the data rate of a single-user DFH is larger than the FFlI data rate. Mostly at low and mid-level SNRs~ Dl-H is more MUItolerant than the comparable FFH and FFII systems with interference cancellation.
