DS/CDMA移动通信中的盲自适应多用户接收技术

Blind Adaptive Multiuser Recieived Technology for DS/CDMA

盲自适应多用户接收技术是ＤＳ／ＣＤＭＡ中抵抗多址干扰和“远近效应”消除的有效方法。本文讨论的最小输出能量盲自适应技术是一种在结构和准则上完全不同于判决反馈近似的方法。它比判决反馈法计算量小，又不要求训练序列，实现了均方误差最小，其性能接近单用户系统，在技术上易于实现。

Multiuser received techniques is an effective stratgies to counter multiuser interfrence and the near-far effcets in DS/CDMA mobile communication systems.A blind adaptive algorithm is discussed,which is different from decision-feedback detector on structure and criterion.It minimizes the energy of output samplesat each symbol interval ,and it converges to the MMES detector without requireing training sequences ,its computations are simple and the performance tends to that of single user system.
