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.)

说明：  Jocobi算法，计算矩阵的特征向量和特征值。(Jocobi algorithm, computing matrix eigenvectors and eigenvalues.)

遗传算法求tsp问题及其matlab代码实现 主程序中有一rand( seed ,n) n 为某一整数, 这是设置随机数发生器的种子，这样实际上规定了随机数发生的方式，因此后面的随机数其实都是定下来的，这样所有人就可以看到同一结果, 可注释掉此行，那么每次的结果就不一定再相同了. (Genetic algorithm to solve the TSP problem and the matlab code to achieve A Rand main program ( seed , n) n as an integer, which is the setting of the random number generator seed, this actually provides a random number generating means, so the random number behind actually are determined, so that everyone can see the same results, can comment out this line, then each time the results do not necessarily the same. )

再传一个瑞利衰落信道，大家可以看看，很有帮助(this is a reigh fading channel)
