摘要：
A method to obtain high diversity gain is proposed by spatial phase coding (SPC) in the cooperative multiple input multiple output-orthogonal frequency division multiple access (MIMO-OFDMA) system. SPC provides improved diversity gain dramatically in proportion to the number of received paths although the one-bit feedback information is used. Moreover, the cooperative MIMO-OFDMA system has received paths without additional antennas more than the conventional MIMO-OFDMA system. Therefore, SPC can improve reliability in the cooperative MIMO-OFDMA system effectively.
