代码说明：

1. 程序中Turbo译码采用了MAP,LOG-MAP，和MAX-LOG-MAP三种算法。 2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数，保存下来的目的是加快仿真的速度，如果你所仿真的Turbo码不是程序中列出的任意一种，你可以通过函数 trellis来生成自己的相关参数。 3. 程序支持1/2和1/3两种码率的Turbo码，其中1/2码率的Turbo码通过矩阵[1 0 0 1]打孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。 4. 程序中的信噪比表示Eb/N0，通过此参数求得N0，对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)

录入程序代码，并对该实验代码进行调试，检查程序代码中的语法和语义错误。编写函数f（x）的代码如下： Romberg算法¨ function z=f(x) if (x~=0) z=sin(x)/x else z=1 end 备注：在实验代码中，首先输入必要的变量的值如下： a=0 b=1 tol=1e-8 待查询检查通过，开始输入执行代码设置格式format short g查看u的值和sin（u）的值： (Input program code, and debugging code for the experiment to check the program code in the syntax and semantic errors. The preparation of a function f (x) of the code is as follows: Romberg algorithm ¨ function z = f (x) if (x ~ = 0) z = sin (x)/x else z = 1 end Note: In the experimental code, First, enter the necessary value of the variable is as follows: a = 0 b = 1 tol = 1e-8 pending inquiries, checking through, began to enter the implementation of the code format format short g see u, values and sin (u) values:)

Optimal-Reconfiguration-of-Distribution
Power distribution systems have tie and sectionalizing switches whose states determine the configuration of the network. Reconfiguration of distribution network is achieved through switching operation on switches of distribution network branches. Power companies are interested in finding the most efficient configuration for minimization of real power losses and load balancing among distribution feeders to save the energy and enhance the operation performance of distribution system. The objective of this thesis is to show that the ant colony optimization algorithm can be used successfully in the reconfiguration of electrical distribution networks to minimize the power losses of the system and to balance the loading of the feeders. This work is to provide a basis for power companies to use it in the reconfiguration of the distribution networks to reduce the operational costs and to enhance the performance of their networks.
