利用一数学仿真工具构建一16-QAM的通信系统 工具：推荐使用Matlab,可使用信号处理工具箱但不能利用通信工具箱(The use of a mathematical simulation tools to build a 16-QAM communication system tools: Recommended use of Matlab, Signal Processing Toolbox can be used but not the use of communication toolbox)

说明：  matlab数字信号处理的好算法，可以对处理数字问题达到简便的效果(a good digital signal processing matlab algorithm can deal with the effect of number of issues to simple)

this projeh learn us how simulate OFDMtransmitter

ou can use this M-file as a guideline for implementing CRC code generation using the Communications Toolbox functionality. This M-file does not include the error detection process, but you can easily use the process specified below to perform the CRC check:

瑞利分布信号直方图的产生已经仿真，已经调试通过。(Rayleigh distribution histogram has generated signal simulation, debugging has been passed.)

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

定时恢复在接收机中是必不可少的环节，只有定时恢复环节性能良好才能正确解调出信号。 位同步-gardner算法(Timing recovery is an essential part of the receiver, and the signal is demodulated correctly only when the timing recovery is in good performance.)

采用有限控制体积法解一维热传导方程，程序简洁明了(Finite control volume method for solution of one-dimensional heat conduction equation, the program concise)

Singulaar spectrum analysis code. (a version of PCA- principal component analysis)
