| Abstract | ||
| In this paper, the performance of a PRAKE receiver for a pulse based ultra-wideband (UWB) communications system is studied in a realistic channel model that is based on an extensive set of indoor channel measurements. The adaptation of parameters of Binary Phase shift Keying/Time Hopping/Ultra Wideband (BPSK/TH/UWB) using PRAKE receiver is shown to contribute to a mitigation of the Inter-pulse interference (IPI). This work is based on the adaptation of multiple access parameters to mitigate the effect of IPI in a certain level. This study is done on the Wireless Personal Area Network (WPAN) IEEE802.15.3a, CM3 channel which is used for indoor network applications. Simulated results show the performance improvement in terms of BER. The results show improvements in the BER due to the adaptation of the values of number of pulses Ns and the number of chips per frame Nh. This is done simply by adjusting the bit rate Rb to a certain value and varies the value of Ns and Nh such that their product has a similar value. In this way the IPI is reduced because it is hardly depends on Ns and Nh | ||
