Performance Evaluation of Impulse Radio UWB Systems with PulseBased Polarity Randomization in Asynchronous Multiuser Environments
(2004) IEEE Wireless Communications and Networking Conference, WCNC 2004 In IEEE Wireless Communications and Networking Conference, 2004. WCNC. p.908913 Abstract
 The performance of a binary phase shift keyed random timehopping impulse radio system with pulsebased polarity randomization is analyzed. The effects of multiple access interference are investigated for both chipsynchronous and asynchronous systems. It is shown that the performance of a chipsynchronous system is the same as that for the symbolsynchronous case studied in E. Fisher and H. V. Poor (Oct. 24, 2002). The asynchronous system is modelled as a chipsynchronous system with uniformly distributed timing jitter on the transmitted pulses of interfering users. This extends the analytical technique developed for the chipsynchronous case to the asynchronous case. An approximate closedform expression for the probability of error,... (More)
 The performance of a binary phase shift keyed random timehopping impulse radio system with pulsebased polarity randomization is analyzed. The effects of multiple access interference are investigated for both chipsynchronous and asynchronous systems. It is shown that the performance of a chipsynchronous system is the same as that for the symbolsynchronous case studied in E. Fisher and H. V. Poor (Oct. 24, 2002). The asynchronous system is modelled as a chipsynchronous system with uniformly distributed timing jitter on the transmitted pulses of interfering users. This extends the analytical technique developed for the chipsynchronous case to the asynchronous case. An approximate closedform expression for the probability of error, expressed in terms of the autocorrelation function of the transmitted pulse, is derived for the asynchronous case. The analysis shows that the chipsynchronous assumption can result in overestimating the error probability, and hence that the system design based on this approximation will he on the safe side. The degree of overestimation mainly depends on the autocorrelation function of the UWB pulse and signaltointerferenceplusnoiseratio (SIR) of the system. Simulations studies support this approximate analysis. (Less)
