摘要

针对多输入多输出(MIMO)正交频分复用(OFDM)系统的时域信道估计问题，提出了一类基于酉变换的最优导频算法。同时，给出了不需要插值的频域信道估计。结果表明，频域方法与时域方法具有相同的性能，且优于插值方法。此外，还提出了实现这些方法的快速算法。仿真结果表明，该方法是有效的

Optimal Pilot and Fast Algorithm for MIMO-OFDM Channel Estimation

In this paper, a class of unitary transform based optimal pilots is found for time domain channel estimation in multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. Also, a frequency domain channel estimation which does not need interpolation is obtained. It is shown that the frequency domain method achieves the same performance as the time domain method and is better than interpolation methods. Furthermore, fast algorithms are proposed to implement the methods. Simulations demonstrate that the methods are effective
