| 摘要: |
| 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。 |

| Abstract: |
| 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. |
| Keywords: smart antennas space-time processing multiuser detection |
