METHOD AND DEVICE FOR ACQUIRING CHANNEL RESPONSE

Document Type and Number:

WIPO Patent Application WO/2016/184200

Kind Code:

A1

Abstract:

A method and device for acquiring channel response. The method comprises: acquiring channel estimations of all carriers from a (n-m)th frame to a (n-1)th frame by means of a sounding reference signal (SRS); carrying out conjugate multiplication on the channel estimations to obtain a cross correlation matrix of all the carriers from the (n-m)th frame to the (n-1)th frame, and estimating cross correlation matrixes between a subframe p of an nth frame and all the carriers from the (n-m)th frame to the (n-1)th frame; filtering all elements Rpq of the cross correlation matrixes of all the carriers; and acquiring channel responses H(n) of all carriers of the subframe p of the nth frame by means of a linear prediction algorithm by utilizing the cross correlation matrixes, n, m and p all being positive integers.
