Performance Analysis of Analog LMS Multiuser receiver in Transmitted-Reference UWB System
Due to the severe and complicated multipath fading of the ultra-wideband (UWB) impulses, it is difficult to theoretically analyze the detection performance of the adaptive multiuser detector. By modulating the reference with a simple pseudo-random code, we have proposed an analog LMS multiuser detection in transmitted-reference UWB system. Here, the steadystate performances of this algorithm are analyzed. In the analysis, the approximations based on the characters of the UWB channel and impulse are introduced. Thus, a closed-form expression for SINR output is derived, and validated by simulation in LOS and NLOS channel respectively. From the theoretic result, the multipath delay spread in line-of-sight (LOS) and non-line-ofsight (NLOS) environments are considered to determine the width of the integration window of the detector.
