Abstract :
Space-division multiple-access (SDMA) has been extensively studied for its increasing the throughput of cellular systems. One transmission antenna uplink SDMA, called cooperative spatial multiplexing (CSM) has been adopted for uplink SDMA in IEEE 802.16d standard [2]. For multiple transmission antennas mobile stations, we propose codebook based uplink transmission and compares its performance with CSM. System level simulation (SLS) for the orthogonal frequency division multiple access (OFDMA) cellular system is done to compare two systems. The proposed scheme results in substantial gain over the CSM in throughput.
