Abstract :
This paper proposes a user selection algorithm in space division multiple access (SDMA) systems. In the proposed algorithm, each user calculates signal to interference plus noise ratio (SINR) taking angle-of-departure, angle-of-arrival, and channel environment with clustering nature into consideration. The base station selects several users who have the high SINR to increase the system throughput. The simulation results show that the proposed algorithm achieves higher throughput compare to the conventional algorithm in SDMA systems.
