SDMA系统FD方案阻塞率的仿真

现代无线移动通信系统广泛考虑采用空分多址（SDMA）多址接入技术来提高系统容量。比如在频分复用（FDMA）时分复用（TDMA）,码分复用（CDMA）。分析研究SDMA系统中的FD信道分配机制,给出了理论推导,并在此基础上进行了仿真。仿真结果表明：采用该机制以后,用户可以在同一时间共享同一信道。

Simulation on Blocking Probability of FD Scheme for SDMA Systems

Space division multiple access（SDMA） is a technique that could 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）.This paper discusses FD channel distribution mechanism and gives the theoretical derivation.Theoretical analysis and experiment simulation on the blocking probability of FD scheme indicate that this mechanism could make the user share the same channel at the same time.
