说明：  QPSK（四进制相移键控）信号调制解调过程（经高斯信道）的仿真(QPSK (quaternary phase shift keying) signal modulation and demodulation process (by the Gaussian channel) of the simulation)

自适应多速率编码器标准代码，编码端。可将wav文件编码生成amr格式的文件。这种格式的文件可根据信道质量，自动调节编码速率，故称之为自适应。(adaptive multi-rate coding standards for code-coding. Wav documents can be generated amr coding format documents. This format of the document is available according to the channel quality, automatic adjustment coding rate, but it is called adaptive.)

BBABssemble(K,k,i,j,m,n)根据单元结点信(i,j,m,n)将单刚阵定位到总刚阵中。(This function assembles the element stiffness matrix k of the bilinear quadrilateral element with nodes i, j, m, and n into the global stiffness matrix K. )

分别给出了带卷积吗，卷积吗-RS吗，RS吗的系统误码率仿真程序( )

这个matlab程序实现了目标对象的图像分割与提取技术，附件里的程序以车牌的检测与识别为例，效果非常好。(The matlab program to achieve the target object' s image segmentation and extraction technology, in the annex of the procedures for license plate detection and recognition, for example, the effect was very good.)
