TRANSFORM-BASED SYSTEMS AND METHODS FOR RECONSTRUCTING STEERING MATRICES IN A MIMO-OFDM SYSTEM |
摘要 |
Embodiments provide a transform-based method for representing steering matrices in transmit beamforming for a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system. Beamforming embodiments generate a transform-based representation of steering matrices for at least a subset of sub-carriers for which channel information is known. In some embodiments, a beamformer is able to receive transform matrices information for at least a subset of channel sub-carriers, and generate corresponding channel sub-carrier steering matrices. Some embodiments of a beamformee are able to map at least a subset of channel sub-carrier steering matrices to corresponding transform matrices information prior to transmitting the transform matrix information to a beamformer. Other embodiments of a beamformer are able to receive channel information for at least a subset of sub-carriers of a channel, and compute a transform-based representation of a steering matrix for each sub-carrier for which channel information is known. |
