Method for generating channel responses of dedicated reference signals, and channel estimation method

The invention provides a method for generating channel responses of dedicated reference signals (DRS) for channel estimation. The method comprises: an initial channel response generation step of generating initial channel responses of at least a part of DRSs in at least one signal frame; a channel response difference determination step of determining differences between every two corresponding initial channel responses for the at least a part of DRSs; a weight generation step of generating weights of the at least a part of DRSs based on the differences between every two initial channel responses and noise power; and a final channel response generation step of obtaining final channel responses of the at least a part of DRSs by utilizing the weights. The invention also provides a channel estimation method and related devices implemented by the method. By the methods and the devices, the influence of noises can be suppressed, the influence of channel change in a time domain and a frequency domain can be reduced, and the noise power and the differences among the channel responses of the DRSs also can be minimized.
