几种主要的线性检测器及性能分析

The Performances Analysis of Decorrelator, MMSE and Matched Filter

在符号同步信道的设定下 ,对解相关算法、最小均方误差算法、匹配滤波器算法等线性接收器实现信号解调的原理作了较细致的讨论 ;对它们的估计误差、信干比以及差错概率等技术指标进行了比较研究 ;从算法的拟合机理上对它们的内在差别作了说明。最后对理论分析的结论作了计算机模拟 ,证实了理论分析的可靠性。

This paper deals with the performances of Decorrelator, MMSE and Matched filter in the synchronous channel compares their estimation errors, signal and interference ratio and the error probability. The paper explains their intrinsic difference from the view point of the fitting mechanism. Finally, the computer simulations show the reliability of the theory.\;
