摘　　要：根据文献[1]中的结论,超宽带信号的设计中,应尽量使信号间的欧几里得距离最大。而文中通过对AW GN信道中利用PPM完成端到端通信的误码率公式及其理论曲线分析,得出结论:脉冲位置调制后的UW B-PPM脉冲相关度为零,是其最佳调制信号的设计条件。进一步地,通过仿真验证了理论推导的正确性,并得到结论:尽量选取拖尾小的基函数作为UW B-PPM通信的信号脉冲。According to reference [1], the maximum Euclidean distance makes BER minimum. This paper deduced the theory of BER for PPM end-to-end communications in AWGN, analyzed the BER curves, and drew the conclusion about optimal condition for the design of modulated signals in UWB-PPM that the correlation between pulses is zero. Furthermore, through simulations, this paper verified the validity of theoretic deduction, and also drew out the conculsion that Small-tailed basic function should be selected to be the signal pulse in UWB-PPM communication.
