摘　　要：对PPM调制的跳时超宽带(TH-UWB)系统性能进行了研究,详细分析了其系统构成及系统性能,并对整个分析结合M atlab仿真工具进行了计算机仿真,验证了重复编码和不同判决方式对系统性能的影响。另外,还给出了采用M进制PPM调制和PAM调制的TH-UWB系统性能理论分析结果。The performance of TH- UWB system modulated with PPM is discussed,in which the system composition and performance are explained. The whole analysis is coupled with MATLAB tools to carry out system performance simulation and the simulation results verify the influence of repeat code and different decision schemes over system performance. Further, the theoretical analysis of M - PPM and M - PAM is carried on to compare the system performance respectively with the two modulations.
