摘要: The performance of a binary phase shift keyed random time-hopping impulse radio system with pulse-based polarity randomization is analyzed. effects multiple access interference are investigated for both chip-synchronous and asynchronous systems. It shown that the same as symbol-synchronous case studied in E. Fisher H. V. Poor (Oct. 2-4, 2002). modelled uniformly distributed timing jitter on transmitted pulses interfering users. This extends analytical technique developed to case. An approximate closed-form expression probability error, expressed terms autocorrelation function pulse, derived analysis shows assumption can result over-estimating error probability, hence design based this approximation will he safe side. degree over-estimation mainly depends UWB pulse signal-to-interference-plus-noise-ratio (SIR) system. Simulations studies support analysis.
