Blocking Probability Simulation Based on SDMA Systems

Abstract

Space division multiple access(SDMA) is a technique that can be superimposed on traditional multiple access schemes to increase the system capacity, such as frequency division multiple access(FDMA), time division multiple access(TDMA) or code division multiple access(CDMA). SDMA technology employs antenna arrays and multi- dimensional nonlinear signal processing techniques to provide significant increases capacity and quality of many wireless communication systems. Several works have been carried out to examine the improvement in the system capacity provided by SDMA. Based on the theoretical analysis and simulate model, the blocking probability of the proposed scheme is simulated and compared in this paper.
