摘　　要：借助接收数据阵的广义左零空间,把发送信号盲恢复问题转换为求解带整数约束的二次规划问题,进而根据盲检测的发送信号辨识传输信道。而且文中方法可以有效地辨识带公零点的SIMO(单输入多输出)信道。仿真结果表明:新算法明显优于现有的文献算法,且辨识含公零点SIMO信道有着卓越的性能表现。The new algorithm change the question of blindly recovering the transmitted signals into the one of quadratic optimization with integer constraints through generalized left null space of received data matrix,and then it can effectively identify the SIMO channel with common zeros through the estimated transmitted signals.The simulation results show that the new algorithm is evidently better than other algorithms in the previous literatures.Moreover,it has the excellent performance in estimating SIMO channel with common zeros.
