To suggestively improve the performance with assured Quality of Service (QoS) for multiple users with adaptive resource allocation, a promising technique namely, multiple antenna Orthogonal Frequency Division Multiple Access (OFDMA) can be proposed with high downlink capacity in the next generation wireless systems under realistic conditions. A transceiver structure is proposed to reduce the interference among transmitting subcarriers and receiving subcarriers, in terms of Signal Interference and Noise Ratio (SINR), which is evaluated by both analysis and simulation methods. And is incorporated into a recently proposed cooperation strategy to examine its performance under the realistic structure for OFDMA systems.
