<p>The present invention provides a method and a device for calculating a coefficient of a time-domain channel estimation filter. The method comprises: acquiring position information and weight information of symbols carrying RS information corresponding to X 1 , X 2 ··· X P ; acquiring position information and weight information of symbols carrying RS information relating to Y 1 , Y 2 ,··· Y Q ; calculating an autocorrelation matrix of a vector I in accordance with the position information and the weight information, wherein I = [ X 1 , X 2 ··· X P , Y 1 , Y 2 , Y Q ]; calculating a crosscorrelation matrix of a vector O and the vector I in accordance with the position information and the weight information, wherein O = [ Y 0 ], and Y 0 is a time-domain channel ideal value of the symbol on which the channel estimation is currently performed; and calculating an inverse matrix product of the crosscorrelation matrix and the autocorrelation matrix, thereby obtaining a coefficient vector corresponding to the symbol on which the channel estimation is currently performed. According to the present invention, it is able to calculate an optimal filter coefficient.</p> |
