Abstract
Based on the new detection criterion proposed in Part 1 for the detecton of weak M-ary signals, a detection scheme for ultra wideband multiple access systems is investigated in the presence of impulsive interference. Simulation results show that the proposed detector, requiring less complexity, possesses almost the same performance as the maximum likelihood detector. In impulsive interference, the proposed detector also offers performance improvement over the detector optimized for Gaussian environment.
