Abstract
Briefly, in accordance with one or more embodiments, a codebook for wireless transmissions may be generated by dividing a codebook into a fixed set of codewords and an adaptive set of codewords. The adaptive set of codewords may be scaled to cluster together and then rotated to be centered or nearly centered about a target. The adaptive set of codewords may then be merged with the fixed set of codewords to provide a hybrid codebook. A codeword from the hybrid codebook may be selected for precoding a transmission to provide a minimum, or nearly minimum, quantization error.
