Abstract: The present invention relates to a reception apparatus. The reception apparatus includes a plurality of reception antennas; and a signal processing unit configured to use reception characteristic of the plurality of reception antennas, wherein the signal processing unit comprises a channel estimation unit configured to respectively estimate a channel response matrix of each signal received via the plurality of reception antennas, and a coding unit configured to define a coding matrix based on an inverse matrix of the estimated channel response matrix, and to obtain a final output signal corresponding to each reception antenna by applying the coding matrix to each received signal.
