摘要：
In the view of the contradiction of the traditional MMSE channel estimation performance and the practical realization complexity, propose an improvement to the original estimation algorithm. A MMSE simplification algorithm in time-domain is presented. Its simulated performance results show that this algorithm has preferable performance and lower complexity. It has better reference value in system practical realization.
