OFDM时域信道估计的MMSE简化算法

MMSE Simplification Algorithm in Time-Domain for OFDM Channel Estimation

鉴于传统MMSE信道估计器性能与实现复杂度的矛盾,提出了一种简化的易于实现的时域MMSE信道估计器,并对其性能进行了仿真。结果表明,该算法有较好的性能,且算法复杂度较低。在系统的实现中有较好的参考价值。

In the view of the contradiction of the traditional MMSE channel estimation performance and the realization complexity, a MMSE simplification algorithm in time-domain is presented and its performance is simulated. The results show that this algorithm has preferable performance and lower complexity. It has better reference value in system realization.
