摘要： The present invention provides data transmission capacity that is optimized in a communication environment by iteratively modyfying a beamforming vector by linearly coupling selfish beamforming with unselfish beamforming using feedback information. The transmitter for modifying the beamforming vector iteratively includes: a feedback receiving module that receives feedback infoprmation from a receiver: and a vector determination module that determines an initial beamforming vector by coupling a first vector for the selfish beamforming with a second vector for the unselfish beamforming at the time of initial beamforming, and corrects a coupling ratio of the first vector and the second vector of the beamforming vector with reference to the received feedback information whenever the beamforming is modified.

摘要： Provided are a transmitting apparatus and a transmitting method in a multiple input multiple output system. A power allocation controller includes a block Tomlinson-Harashima precoder (BTHP) that precodes and outputs data to be transmitted to each user in a nonlinear scheme. The BTHP removes and outputs inference signals from data for each user based on the channel information that is fed back from the users. The data for each user output from the BTHP are allocated with power by the power allocation controller. The power allocation controller calculates power allocation parameters so that receiving minimum distances at receiving ends for each user that receive data through the MIMO antennas are the same, and allocates the calculated parameters to data for each user.

摘要： In a communication system including a plurality of base stations and a plurality of terminals belonging to each of the base stations, the base station receives information on subcarriers allocated to a terminal that belongs to an adjacent base station from the adjacent base station. Thereafter, the base station generates power control information on the basis of the subcarrier information and transmits the power control information to the terminal, and the terminal controls uplink power on the basis of the received power control information. At this time, the power control information, as information based on estimating hitting between subcarriers used by the terminal that belongs to the base station and subcarriers used by the adjacent base station, may be a ratio found by dividing the total number of subcarriers used by each terminal that belongs to the adjacent base station by the entire number of subcarriers that can be used by the base station.

摘要： The present invention relates to an apparatus and a method for selection of a precoding matrix. In the present invention, a precoding matrix to enable an effective signal-to-noise ratio (ESNR) to have a maximum value with respect to a signal vector that requires retransmission is selected in a codebook and fed back to a transmitter. Accordingly, since the effective signal-to-noise ratio has the maximum value after the signal vector is retransmitted, it is possible to minimize a reception error probability of retransmission.
