Abstract :
A combined codebook constructing method is proposed for beamforming in correlated Multiple-input multiple-output (MIMO) channels, where the codebook is dynamically constructed based on the transmit covariance matrix of the channel. Monte Carlo simulations show performance close to optimal beamforming. Huffman coding is used to further reduce the feedback rate in correlated MIMO system.
