Method for generating channel response of dedicated reference signal, and channel estimation method

The present invention provides a method for generating a reference signal, channel dedicated channel estimation of DRS response includes initial channel response generation step, the initial channel at least a portion of the DRS generates at least one signal frame in response; differences determining step response channel, to determine the initial channel response difference between 22 for at least a part DRS; weight generating steps, differences in initial channel response and noise power generating weights for at least a part of the DRS based; and eventually the channel response is generated, using the weighting to obtain the final channel for at least a part of the DRS response. Methods for performing channel estimation obtained by the above methods and related devices are also provided. The method and device can suppress the influence of noise, and can mitigate the influence of channel changes in the time and frequency domains, and can also minimize the difference between the noise power and the channel response of the DRS.
