Abstract  Abstract

A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords c i where i is a unique codeword index for each codeword ci. Each codeword defines weighting factors to apply to the MIMO signals and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets Si for each codeword ci of the codebook C. Each codeword subset Si defines L codewords cj which are selected from all the codewords ci in the codebook C. The codewords cj in a codeword subset Si are the L codewords in the entire codebook that best correlate with the corresponding codeword ci.
