    摘要: Provided is an apparatus and method for transmitting a channel sounding signal from a user terminal in a multiple antenna system. In the method, a channel for each of a plurality of antennas is estimated. The receiving signal power of each of the antennas is calculated using the channel information obtained through the channel estimation. The antenna with the highest RX signal power is selected. Therefore, it is possible to enhance the signal reception performance of the user terminal.

    摘要: An achievable sum data rate with respect to each of available candidate transmission/reception modes may be calculated to select a transmission/reception mode of transmission/reception pairs repeatedly using radio resources. A transmission/reception mode to be applied may be selected from the candidate transmission/reception modes based on the calculated sum data rate. Information associated with the selected transmission/reception mode may be shared by the transmission/reception pairs.

    摘要: An apparatus and a method for determining an optimum integer perturbation vector of a low complexity in a multiple antenna system include a transmitter that transmits data using an optimum integer perturbation vector of a low complexity in a multiple antenna system includes a module pre-processor, a shift pre-processor, and a precoder. The modulo pre-processor adds an integer perturbation vector to a transmission signal vector. The shift pre-processor phase-shifts a pseudo inverse matrix of a channel matrix using a phase angle. The precoder precodes a transmission signal vector perturbed by the integer perturbation vector using the phase-shifted pseudo inverse matrix of the channel matrix.
