| 摘 要： | 探讨了一种级联结构的空时多用户检测器。它可认为是改进的(或优化的)2D—RAKE接收机或改进的CMOE盲多用户检测器。其结构类似ST2D—RAKE接收机，但能充分利用所需用户的扩频码信息。用优化的方法生成解扩序列，从而大大改善了性能。

| Abstract: | In this paper, a cascade structure of space-time MUD is discussed, which can be considered as an improved (optimized) 2D-RAKE receiver or improved CMOE blind MUD. Its structure is similar to 2D-RAKE receiver, but it can utilize the desired user's spreading code information sufficiently to suppress multiuser interference, that is, the dispreading sequence is optimized based on the information, which improves the performance greatly. |
