  journal={IEEE Journal on Selected Areas in Communications},
This paper first introduces per-path pulse distortion in multiuser detection for ultra-wideband communications. A new generalized RAKE structure that estimates and compensates for the pulse distortion is used. An finite-impulse response filter representation of the per-path impulse response is used and estimated. The new structure greatly improves the system performance. With four users considered in our simulations in a high-rise building environment, it is found that the average performance… CONTINUE READING
