| 摘 要： | 介绍了TH-PPM UWB信号,在AWGN信道和多用户干扰条件下对系统的性能进行了分析,包括误码率分析和系统所能接入的最大用户数,对其误码率进行了仿真.结果表明,随着接入用户数目的增加,系统误码率也增加,而增大重复码长度和脉冲重复时间则可降低系统误码率,但增加脉冲重复时间会降低信息传输速率.

| 关 键 词： | 跳时 脉冲位置调制 超宽带 多址干扰 误码率 |

| Abstract: | The TH-PPM signal is introduced,then the system performance is analyzed over the AWGN channel and MAI interference,including the bit error rate(BER) and the number of users that the system can accommodate.The numerical results of BER are presented in the end.The results indicate that,along with the increasing number of users,the BERs of the system will be increased.But increasing the length of repetition code and the time duration of a frame can decrease the system BER,while the increase of time duration of a frame will reduce the rate of the information transmission. |
