MIMO-CPSC系统中预编码盲信道估计算法研究

摘要

This paper proposed a precoding blind channel estimation for multi-input multi-output single carrier cyclic prefix (MIMO-CPSC) systems. The proposed algorithm exploited the channel information in the cross-correlation matrix of two consecutive received blocks to estimate the channels. This method has low computational complexity and is robust to the channel order overestimation. Simulation results show that the proposed algorithm archive a reliable estimation of channels with fewer received blocks.%针对多天线单载波循环前缀系统,提出了一种基于预编码的盲信道估计算法.该算法通过分离出连续两个接收符号块的互相关矩阵所包含的信道信息实现信道盲估计.仿真结果表明,该算法具有较低的计算复杂度以及对信道阶数过估计有很好的鲁棒性,并且该算法利用较少的数据块个数就得到了一个可靠的信道估计值.
