对SDMA空分多址系统的两种信道分配方案进行仿真，比较其性能，主要是阻塞率性能仿真。 附件里面的两个源程序分别为两种编程思想。

The use of space-division multiple access (SDMA) in the downlink of a multiuser multiple-input, multiple-output (MIMO) wireless communications network can provide a substantial gain in system throughput. The challenge in such multiuser systems is des

SDMA的仿真程序，并且用MATLAB实现-SDMA' s simulation program, and use MATLAB to achieve
