摘要

只要单输入多输出(SIMO)信道的公因式满足本文提出的充分必要条件

那么本文方法就可以有效地辨识这些带公零点的信道.本文算法由以下步骤组成:先借助整数约束二次优化盲检测属于给定字符集的发送信号

然后根据这些估得的发送信号辨识传输信道.仿真结果表明:本文新算法明显优于现有的文献算法.

Abstract

The new approach is applicable to identify various SIMO transmission channels with common zeros if only the common factor of those channels satisfies a sufficient and necessary condition presented by our paper.The new approach consists of the following stages:firstly

transmitted signals in given alphabets are blindly detected by using a quadratic optimization with integer constraints; then

the SIMO transmission channels are identified on the basis of the estimated signals.Simulation results show that the new approach delivers better performance compared with the ex isting approaches.
