Abstract
This paper studied on the UWB communication system based on parallel combinatory spread spectrum ( PCSS UWB) of TH MPAM modulation and TH MPPM modulation, and gave the studies and contrast analysis. On the foundation of the structure of PCSS UWB communication system, the symbol error rate of demodulation, performance of de-spread and bit error rate(BER) of the system were analyzed and simulated. And the results show that the BER performance of the system of TH MPAM mode is better than that of TH MPPM, because of the matching of the imbalance of multivalued symbols demodulation and non-equal probability of the parallel combinatory spread spectrum signals, which could ensure the performance of de-spread.关键词
