试说明卷积编解码的工作原理。 请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编解码全部自己编写代码(S-Function方式)，在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。 (Description Convolutional codec test works. Please use Simulink simulation of convolutional coding and Viterbi decoding method used to decode, which codec to prepare all their own code (S-Function mode), in the AWGN channel, drawn-noise ratio and bit error rate curve.)

这个程序是采用牛顿法来进行潮流计算，系统的参数需要手动输入，相关的说明在程序里有,需要输入两个矩阵，节点和线路的矩阵(This program is the use of the Newton method for power flow calculation, the parameters of the system need to manually enter the description in the program)

说明：  信号处理卷积计算，开发环境是MATLAB.(Convolution signal processing terms, the development environment is MATLAB.)

说明：  对常见的调制信号在软件无线电的通用平台下进行调制解调。所有信号均通过正交分解后，在一个同用的平台上进行调制，然后通过各自的解调算法解调。(right common modulation radio signals in the software under a common platform for modulation and demodulation. All signals are orthogonal decomposition, the same one used on the platform for modulation and demodulation through their respective demodulation algorithm.)
