摘要

在DS/CDMA系统中，噪声过程中含有脉冲分量，采用了鲁棒单用户检测。计算了混合噪声模型的击穿点。当信号功率较低时，噪声而不是干扰是实现良好性能的主要障碍。在高斯混合条件下，导出了误码概率表达式。采用鲁棒相关接收机的DS/CDMA在脉冲噪声环境下的性能优于传统的匹配滤波器。

Performance of robust single-user detection in DS/CDMA systems

Robust single-user detection is employed in a DS/CDMA system in which the noise process contains impulsive components. The breakdown point is computed for a mixture noise model. Noise rather than interference is shown to be the primary obstacle in achieving good performance when the signal power is low. The bit error probability expressions are also derived under a Gaussian mixture. DS/CDMA employing a robust correlator receiver performs better than the conventional matched filter in impulsive noise environment.
