Title: Analysis on UWB Ambipolar Multi-pulse Position Modulation
Abstract: A new UWB (ultra-wideband) modulation scheme called L-ary UWB-TH-AMPPM (Time hopping Ambipolar multi-pulse position modulation) was proposed to get a better UWB communication performance, and the ECWC (extending constant weight code) was introduced to construct the AMPPM signal. The comparison between AMPPM, SPPM (single pulse position modulation) and BPPM (biorthogonal pulse position modulation) was given in four aspects which are data rate, power efficiency, bandwidth efficiency and probability of symbol error respectively. Theory analysis and numerical results show that when the ECWC is chosen rightly, AMPPM can achieve better UWB communication performance than both of the SPPM and BPPM under the same condition.
