Abstract
In this paper, a new receiver with low complexity for a DS-UWB system which can eliminate efficiently the multiple access interference and the detrimental effects caused by multi-paths is proposed. The performance of conventional DS-UWB receivers depends greatly on the types and lengths of spreading codes. Generally, as the length of spreading codes increases, the receiver performance improves. But, the receiver performance does not improve satisfactorily in a multi-paths fading environment. Through computer simulations, it can be shown that the proposed DS-UWB receiver eliminate the multi-paths effects efficiently in a multi-user, multi-paths fading environment, and the user capacity can be increased dramatically using the proposed receiver.
