中文摘要：

跳时双正交脉冲位置调制（TH-BPPM）在超宽带（UWB）衰落信道的通信系统性能研究是基于超宽带室内无线信道进行研究的。频率选择性衰落是多径环境需要重点考虑的因素之一,在单用户情况下经常采用高斯近似法。利用等效瞬时信噪比和在AWGN信道下的误码率公式推导得出错误概率公式,并由Matlab仿真得到结论。

英文摘要：

The performance of time-hopping biorthogonal pulse position modulation（BPPM） for communication system of an ultra-wideband（UWB） fading channel is investigated based on the multipath fading statistics of UWB indoor wireless channel.Frequency selective fading is considered for a multiple access environment,Gaussian approximation method is usually used based on a single user mode.Error probability expressions are derived from equivalent instantaneous signal to noise ratio（SNR） and the bit error rate formula in AWGN channel.The results are verified by Matlab simulation.
