%X This paper proposed a channel estimation algorithm for 3GPP Long Term Evolution(LTE) uplink.In order to reduce the loss of channel energy in the noise suppression process,the proposed algorithm detected the energy for the time-domain result of the Least Square(LS) algorithm by the method of searching from the middle to both sides.Simulation shows that,comparing to the LS algorithm,the traditional DFT based channel estimation algorithm,the Linear Minimum Mean Square Error(LMMSE) algorithm and negative-exponential LMMSE algorithm,the proposed algorithm has good performances and is prone to implement,which has strong practicability.
