摘要 在加性高斯白噪声信道和多用户干扰条件下,介绍了DS-PAM UWB信号及基于高斯近似法的DS-PAM UWB系统的多址接入误比特率公式,然后分析了影响DS-PAM UWB系统多址接入性能的因素。结果表明,随着用户比特速率和接入用户数的增加,系统的误比特率也增加,而增大重复码长度可降低系统误比特率。 The DS - PAM UWB signal and the bit error rate formula of DS - PAM UWB system multiple access based on Gaussian approximation method is introduced over the Additive White Gaussian Noise channel and Multiple Access Interference,then the factors of affected DS -PAM UWB multiple access performance is analyzed , the results indicate that,along with the increasing bit rate of user and number of users, the Bit Error Rate of the system will be increased, but increasing the length of repetition code can decrease the system BER.
