此代码是用matlab进行AF协作的性能的仿真对误码率进行分析。

cdma系统的仿真程序，可以在此基础上研究cdma系统的各种环境下的性能，改程序已经验证过-cdma system simulation program, in this study based on the CDMA system under various environmental performance, change procedures have been tested

QAM调制的基本原理 QAM调制实际上是幅度调制和相位调制的组合。相位 + 幅度状态定义了一个数字或数 字的组合。QAM的优点是具有更大的符号率，从而可获得更高的系统效率。通常由符号率 确定占用带宽。因此每个符号的比特（基本信息单位）越多，效率就越高。-QAM modulation of the basic principles are in fact QAM modulation amplitude modulation and phase modulation of the portfolio. Phase+ margin status defines a combination of numbers or figures. The advantage of QAM symbols are greater rate, thus the system efficiency will be higher. Symbol rate is usually determined by the occupied bandwidth. Thus each bit symbols (basic units of information) the more the higher the efficiency.

这个是windows版本的.就是用串口通讯线将两台机子用串口连起来进行通讯，最简单的。比如在a机上输入一个字符，在b机上能显示出来 -This is a windows version of the. Serial communication is to use two machines will be used for serial-link appear, the most simple. For example, in a plane into a character, b plane will display
