A study on a channel allocation scheme with an adaptive array in SDMA
This paper describes spatial division multiple access (SDMA) using an adaptive array. A spatial correlation coefficient is proposed as a criterion to determine the possibility of duplicate channel allocation. When the average input SNR is more than 20 dB, the users satisfying a correlation coefficient of less than 0.9 can be accommodated in the same channel in a 2-user SDMA model with a 2-element adaptive array. The blocking rate performance shows that this 2-user SDMA can improve channel efficiency almost twice.
