多径条件下的空时解相关接收机研究

摘要

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.%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。
