Abstract

Ultra-wideband(UWB) system is recently becoming very attractive candidate for low cost short range communication, due to recent development in high speed intelligent switching technology. In this paper, we theoretically analyze the probability of error for M-ary pulse position modulation (PPM) ultra-wideband (UWB) multiple access system using intelligent pulse shaping techniques. We first consider the optimum detection of UWB signals using M-ary orthogonal PPM in additive white Gaussian noise (AWGN). Then we derive receiver signal to noise power ratio (SNR) and bit error rate (BER) in multiple access interference (MAI) environment. Numerical results considering some practical parameters are presented and the BER performance according to different pulse shapes are compared.
