对应论文写的时空码的仿真程序。为2天线，BPSK调制模式。自己写的Space time code simulation提供给大家(Papers written in the corresponding space-time code of the simulation program. 2 antennas, BPSK modulation mode. Write your own Space time code simulation available to the U.S.)

802.11a物理层在matlab上的仿真图，有18M，24M，36M,54M的速率自适应选择.(802.11a physical layer in the matlab simulation on the map, there are 18M, 24M, 36M, 54M of rate-adaptive selection.)

这是美国数学建模的论文，描述了如何用matlab解决问题(American Mathematical modeling is a paper that describes how to use matlab to solve the problem)

说明：  物元分析法由我国数学家蔡文在 20 世纪 80 年代提出． 应用物元法建立多指标评价模型，可以针对复杂问题建立形象化模型，定量化得出评价结果，从而较完整、准确地反映事物的综合水平。利用matlab编程，进行如下步骤计算：1、待判物元的确定；2、经典域、节域的确定；3、关联函数；4、综合关联度(Matter-element analysis method was put forward by Chinese mathematician Cai Wen in 1980's. Applying matter-element method to establish multi-index evaluation model can establish visualization model for complex problems and quantify the evaluation results, so as to reflect the comprehensive level of things more completely and accurately. Using MATLAB programming, the following steps are calculated: 1. determination of the subject element to be judged; 2. determination of classical domain and node domain; 3. correlation function; 4. comprehensive correlation degree)
