Abstract

A transmitter, including: a plurality of antennas; and a controller configured to: receive a first steering matrix for a first feedback tone; receive a second steering matrix for a second feedback tone; estimate an ideal second steering matrix including: estimating a set of random phasors applied to the columns of the second feedback matrix; and estimating a set of row-dependent delays applied to the rows of the second feedback matrix; estimate a vector of angles based upon the estimated set of random phasors; and calculate a steering matrix for a tone between the first feedback tone and the second feedback tone by interpolating between the first steering matrix and the ideal second steering matrix based upon the estimated vector of angles.
