摘要 针对移动通信中的多入多出(MIMO)系统,提出了一种新的基于子空间的半盲信道估计算法。该算法对于连续的2个接收数据块,重新构造一组新的向量而不改变系统的信道矩阵,比较适合于对频率选择性信道的半盲估计。通过仿真比较了该算法与现有半盲信道估计算法的性能。仿真结果表明,该算法利用较少的导频符号可以得到较好的误码性能。 In this paper, we proposed a new semi-blind channel estimation algorithm of MIMO chan- nel. The proposed method is very suitable for semi-blind estimation of the frequency selecting channels. Compared with some existing methods, the proposed algorithm can achieve better performance than existing methods.
