Suppression of interference in time domain equalizers is attempted for high data rate impulse radio (IR) ultra wideband communication system. The narrow band systems may cause interference with UWB devices as it is having very low transmission power and the large bandwidth. SRAKE receiver improves system performance by equalizing signals from different paths. This enables the use of SRAKE receiver techniques in IR UWB systems A semi analytical approach is used to investigate the BER performance

Study on non-line of sight indoor channel models (both CM3 and CM4) illustrates that bit error rate performance of SRake receiver with NBI performs better than that of Rake receiver without NBI Keywords -Bit error rate, Impulse radio, Non-line of sight, SRAKE receiver, Ultra wideband (UWB)
