盲自适应的多用户CDMA阵列接收机

A Blind Adaptive Multiuser CDMA Array Receiver

研究了基于CMOE准则的空时多用户检测及其自适应实现。这是一种盲方法 ,不要求任何训练序列 ,能够抑制多址干扰 ,解决远近效应问题。进一步 ,分析了多用户CDMA阵列接收机的性能 ,并且与多用户单天线接收机、单用户阵列接收机以及单用户单天线接收机进行了比较。

Space time multiuser detection based on constrained minimum output energy and its adaptive implementation are studied. This is a blind method which can suppress the multiple access interferences and solve the near far problem without any training sequences. Furthermore, performances of the multiuser CDMA antenna array receiver are analyzed and compared with the performances of the multiuser single antenna receiver, the single user array receiver and the single user single antenna receiver.
