| Abstract: | In this paper,the author introduced estimation algorithm of LS channel and estimation algorithm of time-domain filtering,and simulated two algorithms in the condition of giving training sequence and channel model.The author put forward another algorithm of time-domain filtering when the first algorithm of time-domain filtering couldn＇t match channel model,which improved performance of MSE of channel estimat. |
