多用户DS-CDMA系统接收机载波频偏的有效估计方法

An Efficient Estimation Method of Carrier Offset in Multi-user DS - CDMA System

多用户DS-CDMA系统中用户检测器存在小残差载波频偏,在对接收机模型分析基础上,给出一种基于通用特征值问题的有效估计载波频偏的方法。仿真结果表明该方法不但有效可行,同时还可估算出多用户DS-CDMA系统的信道响应。

In Multi-user DS - CDMA system user detectors produce a small residual carrier offset, based on the analysis of the receiver's model, an efficient estimation method of carrier offset is presented. Simulations on computer show that the method is effective, feasible and can be used to estimate the channel's response in DS - CDMA.
