Abstract:

In selecting access terminals (AT) for simultaneous transmission, the effectiveness of the spatial-domain scheduler is one of the key factors that affect the performance of the space division multiple access (SDMA) based wireless packet cellular system. The forward link throughput of an SDMA based wireless packet cellular system, to the ability of our proposed quasioptimal weight priority scheduling and beam forming scheme, was evaluated under a condition that is similar to the field environment. The optimal AT directional separation conditions which promise the maximum median cell throughput have been obtained. Simulation results show that more than 10 times the total cell throughput is obtained over that of the system with an omni-antenna. The typical base station equipped with a three-sector antenna can get no more than 3 times the throughput of that with omni-antenna; therefore, the SDMA based wireless packet cellular system discussed has great potential in the future of wireless high-speed data communication.
