| Abstract: | As users increase and the bandwidth to pulse repetition frequency(PRF) decreases in UWB-MA communication,multiple-access interference(MAI) is expected to adversely affect system capacity and performance.This paper investigates multi-user detection in multiple-access communicaton systems based on ultrawideband(UWB) technology.Simulation results show that the performance of proposed multiuser detector is better than of the conventional detector. |
