摘　　要：在多脉冲位置调制的基础上,提出一种加入脉冲极性的超宽带多脉冲组合调制方案,利用扩展等重码构建一种称为双极性多脉冲位置调制(MPPPM)的UWB跳时调制方案,并对其信号构建、调制做了设计,对其通信性能进行了分析与比较。结果表明,在一定的条件下,MPPPM调制技术能以较高的数据速率和较低的误码率得到比多脉冲位置调制和单脉冲多位置调制更好的性能。利用多脉冲组合调制下信息容量大的优点,分析在高斯白噪声信道下的误码率公式,从而能更加深刻地了解和分析MPPPM的性能。A scheme employing Multiple -pulse Position and Polarity Modulation（MPPPM） constructed by Extended Constant Weight Code（ECWC） to increase the number of available signal for the same symbol interval compared to the conventional system is proposed. It designs the signal construction and modulation, and also gives the analysis and comparison to the communication system. Theory analysis results show that MPPPM can get better communication performance than single pulse position modulation and multi - pulse amplitude modulation with higher data rate and lower receiver complexity under some given condition. Using the advantages of large capacity information under the modulation on MPPPM to analyze the BER formula at AWGN channel,so that it can more deeply understand and analyze the performance of MPPPM.
