1. A wireless communication system including a plurality of transmitting antennas and a plurality of receiving antennas through which signals are transmitted and received, the wireless communication system comprising:

  • a transmitter that restores feedback information from a predetermined feedback signal, weights an information signal with the restored feedback information, and converts the weighted information signal to a radio frequency signal in order to transmit the radio frequency signal; and

    a receiver that receives the radio frequency signal to estimate the state of a channel through which the radio frequency signal is transmitted, calculates a weight of a dimensionality corresponding to the number of the transmitting antennas, approximates the weight as lower-dimensional one to extract feedback information, and converts the feedback information into a radio frequency signal to send the radio frequency signal to the transmitter.
