CHANNEL INFORMATION GENERATING DEVICE AND METHOD FOR SPATIAL DIVISION MULTIPLEXING ALGORITHM IN A WIRELESS COMMUNICATION SYSTEM, AND DATA TRANSMISSION APPARATUS AND METHOD ADOPTING THE SAME

摘要

Disclosed are a channel information generating device and a method for spatial division multiplexing algorithm in a wireless communication system and data transmission apparatus and a method adopting the same.  According to one embodiment of the present invention, a channel information generating device for space division multiplexing algorithm in an orthogonal frequency division multiplexing (OFDM)-based wireless communication system using multi-input/multi-output (MIMO) antennas comprises: a codebook storage where pre-defined codebooks are stored; a channel correlation information calculator which receives channel information corresponding to each of the sub-carriers and calculates information on a channel correlation coefficient between the sub-carriers, based on the received channel information; an index calculator which calculates an index of an optimal matrix out of the matrices stored in the codebook storage, based on the channel information, the channel correlation coefficient information and the codebook; and a transmission section which transmits to an opponent transmitter the channel correlation coefficient information and index information on the optimal matrix.
