针对多用户检测中的多址干扰(MAI),给出了改进信息最大化(I_infomax)的盲多用户检测算法.该算法利用扩频码初始化学习向量,实现了多用户的盲检测.仿真结果及分析表明,算法在误码率、收敛速度和用户容量等方面优于Infomax算法及传统盲多用户检测算法.
An improved Infomax blind multi-user detection method is presented for multi-access interference (MAI). The method initializes the learning vector by utilizing spreading code sequence to blindly detect multiple users. Simulations and analysis indicate that Idnformax is better than Informax and other blind multi-user detectors in bit error rate, convergence speed and user capability.
