| Abstract: | 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. |
