ofdm正交频分复用系统误码率ber，比较简单，基础框架(the ber of ofdm system)

利用幂法求矩阵特征值，属于数值解法的一种(Using power method to find eigenvalues of matrices, which is a kind of numerical solution.)

说明：  这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)

基于matlab的ask调制模块，只需要调用，是具体调制过程，可以自己定义键控的进制(Ask modulation based on the matlab module, only need to call the process of modulation is specific to their own definition of the M-ary keying)

This function will display 2 input images in a single output image, side by side.
