摘要: |
通过建立了一般的空时CDMA系统模型,探讨多址干扰和多径效应的联合抑制问题。首先分析了系统的可辨识条件,然后利用多约束最优化准则研究了FIR空时解相关接收机设计和实现,并进一步分析了系统性能。 |

Abstract: |
A general space-time CDMA system model in multipath fading channels is built to study how to suppress both multiple access interference (MAI) and multipath fading. Identification conditions are first studied. Then a FIR solution of space-time decorrelating receivers is implemented by an optimal criterion with multiple constraints and system performances are analyzed. |
Keywords: CDMA multiuser detection space-time processing MAI multipath fading |
