Simulating Model of UWB System for SUI Channel
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 9
Abstract
This paper is concerned about the performance of UWB system in the multiuser environment. The existence of several multiuser access can cause a significant performance degradation and hence the transmission rate. In this paper, an adaptive least bit error rate (LBER) Rake receiver used for synchronous CDMA UWB system for SUI channel modelling to mitigate multiple access interference and inter symbol interference. Combining weights of Rake receiver is adapted based on the LBER criteria and calculate the cumulative results.BER performance of the conventional MRC,MMSE and LBER Rake receiver can be studied by varying the number of fingers for different number of users and also compare with SUI channel. The conditional probability density function for the output signal is generated to analyze the effect of MAI and ISI at the receiver side. The proposed LBER Rake receiver with SUI channel shows that receiver can suppress MAI and ISI more effectively and also have the lowest path loss in the multiuser environment hence increases the number of active user and transmission rate.
