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
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 existing approaches.
