生成LDPC

这个Matlab程序实现最速下降算法。最速下降法是一种最基本的算法，它在最优化方法中占有重要地位.最速下降法的优点是工作量小，存储变量较少,初始点要求不高；缺点是收敛慢，最速下降法适用于寻优过程的前期迭代或作为间插步骤，当接近极值点时，宜选用别种收敛快的算法. (Matlab implementation of this procedure steepest descent algorithm.)

该程序是自己编写的，是基于matlab的多径信道的建立。该多径信道是基于电力线信道特性而构建的，其中的衰落系数是通过阅读大量文献而得到的。该程序能够顺利运行，并画出了信道的各个参数图。(The program is written by myself,which is to build a multi-path channel matlab based. The multi-path channel is based on the characteristics of the power line channel constructed, which is fading coefficients obtained by reading a lot of literature. The program can run smoothly, and draw a diagram of each parameter channel.)

这个代码是一个模拟到USB协议使用MATLAB生成随机比特和调制它，然后该信号被接收和解调

主要是用于产生ofdm当中有关信道的相关内容(OFDM is mainly used to produce them on the channel content)
