<p>Disclosed are a method and device for estimating a channel in a multiple-receiving antenna system. The method comprises: a channel estimation is performed on a received pilot signal by using a least square channel estimation algorithm to obtain an estimation value H LS ; an N'-dimensional channel autocorrelation matrix formula (I) and a channel frequency domain autocorrelation matrix R i from a transmitting antenna i to any receiving antenna are acquired, and a weight matrix W which is descrambled and denoised is calculated, wherein i=1, 2,..., N T , and N T is the number of antennae at a transmitting end; the estimation value H LS is corrected by using the weight matrix W to obtain a corrected estimation value H P-LMMSE . The device comprises: an initial estimation component, a weight calculation component, and an estimation correction component. The method and device of the present invention may obtain the performance as close as possible to the LMMSE technology through less prior statistic information, and have a simple implementation manner, thereby improving the efficiency of channel estimation.</p> |
