| 摘 要： | 介绍了TH-UWB信号模型,推导出了在AWGN信道条件和多径条件下,重叠和正交脉冲信号下的TH-BPPMUWB系统的误码率公式,并进行了仿真。仿真结果表明在AWGN信道条件下,基于重叠脉冲信号的TH-BPPM系统性能优于基于正交脉冲信号的TH-BPPM;多径条件下的正交TH-BPPM的系统性能优于AWGN信道条件下的系统性能。

| Abstract: | This paper introduced the TH-PPM UWB signal firstly, then derived the BER formula of the overlapped and orthogonal pulse signal TH-BPPM UWB system in AWGN channel and multi-path condition, and gives the simulation results. The results show that on the AWGN channel conditions, overlapped-based pulse signal TH-BPPM have a superior system performance to orthogonal based TH-BPPM pulse signal. On multi-path, conditions the orthogonal TH-BPPM system performance superior AWGN channel. |
