The invention discloses a method for
signal channel
estimation denoising post-treatment in a multiantenna
system, which comprises the following steps: obtaining a
signal channel
estimation result * of the multiantenna
system, wherein the
signal channel
estimation result * comprises signal channel estimation results * of K users, namely, *=[ *1, *2, ellipsis, and *K], and k=1, 2, ellipsis, and k; obtaining a
beamforming combination result *K of the multiantenna signal estimation of a user k and sequentially arranging the
beamforming combination results of the users to obtain a
row vector *=[*1,*2, ellipsis, and *K]; denoising the
row vector * to obtain a denoised signal
estimation result *; and according to a tap position set to zero in the denoised signal
estimation result *, setting a corresponding position in the signal
estimation result * to zero and outputting the signal estimation obtained after zero setting. The invention also discloses a device for signal channel estimation denoising post-treatment in the multiantenna
system. The proposal of the invention can fully use the denoising capacity of multiple antennae and effectively improve the accuracy of the signal channel estimation denoising post-treatment.
