UWB High Data-Rate Wireless Communication System Base on Multi-Pulse Position Modulation

In this paper, we propose a new modulation scheme called L-ary multi-pulse position modulation (L-ary MPPM) for ultra-wideband (UWB) high data-rate wireless communication systems. MPPM is an improved pulse position modulation(PPM) by employing multiple pulses and constant weight code to provide a better system performance with comparison with L-ary single-pulse position modulation (SPPM). The error probability and maximum reliable communication distance bounds for MPPM are derived over an AWGN channel and under FCC part 15 rules respectively. Theory analysis and simulation results show that L-ary MPPM can get lower error probability, longer reliable communication distance and larger data rate than L-ary SPPM under the same condition
