摘要

采用长度为32和64的随机二进制签名码，研究了基于DS/CDMA通信系统的最佳单用户检测器(OSD)。通过蒙特卡罗模拟得到了50%和100%的频谱效率。结果表明，OSD的性能明显优于匹配滤波检测器(MFD)，但复杂度略有增加。还可以看到，由于MAI抵消引起的噪声增强降低了OSD的性能。

MAI cancellation by optimum single-user detection for DS/CDMA systems using random binary codes

The optimum single-user detector (OSD) for a DS/CDMA based communications system is investigated using random binary signature codes of length 32 and 64 chips. The BER performances are obtained by Monte-Carlo simulation for spectral efficiencies of 50% and 100%. Results show that the OSD performs significantly better than the matched filter detector (MFD) with a modest increase in complexity. It is also seen that noise enhancement is induced due to MAI cancellation which degrades the OSD performance.
