| 摘 要： | 1 Introduction UWB technology is considered to be a good candidate for future short-range high-data rate wireless communications 1, 2], and modulation plays an important role in UWB wireless communication systems. There are several modulation schemes possible for UWB, such as pulse position modulation (PPM), pulse amplitude modulation (PAM), On-Off keying (OOK), binary phase-shift keying (BPSK), and so on. Reference 3] provides the analysis result of the different modulation methods…

| Abstract: | A new ultra-wide band (UWB) modulation scheme called L-ary ultra-wide band time hopping multi-pulse position modulation (UWB-TH-MPPM) is proposed for high data-rate wireless application, which can provide better communication performance. The constant weight code is introduced to construct the MPPM signal and the comparison between MPPM and single pulse position modulation (SPPM) is done in three aspects, namely, power efficiency, bandwidth efficiency, and probability of symbol error, respectively. The theoretical analysis and the numerical results show that when the constant weight code is appropriately chosen, MPPM can achieve lower probability of symbol error and higher power efficiency than SPPM at the cost of more bandwidth under the same condition. The proposed MPPM can be a good candidate in UWB system design. |
