摘要 基于多输入多输出正交频分复用(MIMO-OFDM)系统的LS信道估计算法,提出一种基于加窗的LS迭代信道估计算法,利用对信道频域响应进行加窗,降低了实际MIMO-OFDM系统信道估计中的信道冲激响应(CIR)泄漏,从而使利用时域低通滤波进行噪声直接删除的方法变得有效。理论分析与仿真实验表明:提出的算法能够比传统的LS信道估计算法获得更高的估计精度。 LS channel estimation method based on Multiple Input Multiple Output -Orthogonal Frequency Division Multiplexing （ MIMO - OFDM） system is studied to present a Least Squares （LS） iterative algorithm based on windowing. The frequency domain windowing is used to reduce the leakage of Channel Impulse Response （CIR） for the practical MIMO - OFDM system so that the noise in direct cut according to a low pass filter is more effective in the time domain. Theoretical analysis and computational simulation results indicate that the proposed algorithm can acquire higher estimation accuracy compared to the traditional LS channel estimation.
