本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法。此文件为咬尾编码矩阵生成的测试文件包(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm. This file is biting the end of the generated test code matrix package)

This is the collection of matlab files for recognition purposes.

用于信号特征提取、信号消噪，用MATLAB编写的遗传算法路径规划，采用加权网络中节点强度和权重都是幂率分布的模型。( For feature extraction, signal de-noising, Genetic algorithms using MATLAB path planning, Using weighted model nodes in the network strength and weight are power law distribution.)
