Abstract :
Investigates the performance of a hybrid DS/SFH spread spectrum multiple access communication system using BPSK modulation over a mobile radio channel in the presence of interference and noise. A decision feedback equalizer (DFE) which provides inherent diversity in a multipath environment is utilized at the receiver. The DFE is also known to significantly reduce cochannel interference and intersymbol interference. Simulation results are presented with minimum mean square error (MMSE) and bit error rate as performance measures
