In this paper we have proposed the algorithm based on ultra wide band (UWB) system which is applied on multiuser detection for wireless personal area network. We have measured bit error rate with respect to signal to noise ratio for pulse amplitude modulation (PAM) and pulse position modulation (PPM) technique based on different number of users. In the proposed algorithm interference is very low compared to conventional algorithm. By varying the number of users we have measured the bit error rate. As we increased the number of users the proposed algorithm detects signal efficiently compared to conventional algorithm. The proposed algorithm is based on the more fading environment that is where the fluctuation of amplitude, phase and delay is more and we have considered Rayleigh Channel. The simulation is based on the MATLAB software.
