Abstract
A method of designing a codebook for analog beamforming. In some embodiments, the method includes: generating a plurality of training points, based on a predefined distribution, each training point being a channel vector; generating, for each of a plurality of codewords, a respective initial value; assigning, in a first assignment operation, each of the training points to a respective desired codeword, the desired codeword maximizing a metric function of a beamforming gain for the training point over the codewords; updating, in a first updating operation, each of the codewords according to the training points assigned to it; and determining whether convergence is achieved; and in response to determining that convergence is achieved, determining a final codebook.
