Home eNode B channel estimate post treatment method and device as well as receiving method and receiver

The invention discloses a home eNode B channel estimate post treatment method and a device as well as a receiving method and a receiver; wherein, the channel estimate post treatment method comprises the steps as follows: after obtaining original channel estimate results by the channel estimate method, adjacent channel estimate tap power and two maximal tap positions are searched out in the channel estimate results of the user; the adjacent channel estimate tap power and the two maximal tap positions are maintained, and other taps are set to be noise taps; the two tap values which are searched out are compared with the preset threshold; if the tap values are higher than the threshold, the tap is judged to be a signal tap, the value of which is maintained; if the tap values are lower than the threshold, the tap is judged to be the noise tap and is set as the noise tap, and the channel estimate post treatment is finished. The invention can completely utilize the specificity of the scene of TD-SCDMA home eNode B and effectively improve the accuracy of channel estimate, thus improving the performance of the receiver.
