摘　　要：多用户检测技术在一定程度上解决了CDMA系统的远近效应,但无论是线性还是非线性多用户检测器,都存在一定的不足和缺陷。将免疫克隆算法应用到多用户检测技术中,并且在同步CDMA系统中进行了仿真。仿真结果表明采用免疫克隆算法的多用户检测器的性能与其他几种算法相比有明显改善。Multi-user detection technology has in a certain extent solved the CDMA system＇s near-far effect. But whether multi-user detectors are linear or non-linear, there are some deficiencies and shortcomings. The immune clone algorithm is applied in multi-user detection technology and simulated in the synchronous CDMA system. Simulation results show that the multi-user detector based on the immune clone algorithm achieves better performance compared with other algorithms.
