摘　　要：简要介绍了超宽带无线通信中PPM、PAM、OOK及BPSK二进制跳时扩频调制技术的实现原理，给出了高斯信道环境下多用户系统的误码率性能，并对其发送信号的功率谱及在高斯信道下的误码率性能进行了仿真，最后指出，TH-BPSK易实现且具有较好的性能。This paper introduces the method used in binary time-hopping spread-spectrum modulation technology of ultra-wideband communication for PPM、PAM、OOK and BPSK. After discussing the multiple access performance of BER in AGWN channel, it simulates the power spectrum of the transmitted signal and the BER in AGWN channel, we thus point out that the TH-BPSK is the best one to be implemented and has better performance as well.
