pso解决两目标函数极值问题，适合初学多目标的同学(Pso solve two goals for beginners, the function extreme problem multi-objective classmates)

极化码中的编译码，以及高斯信道，调制方面的编程(a sort of polar code in AWGN)

有限自动机的确定化及化简 1、更正了 DFA_simplify2 中的错误 2、增加新旧状态对照表 ds_temp --NFA转DFA -- 输入字符 -- 要求 id 必须从 1 开始连续递增(Finite Automata and the identification of a simplification, correction of the errors DFA_simplify2 2, increase the old and new state CRT ds_temp-- NFA to DFA-- input characters-- must request id Start an incremental)

在认知无线电中，频谱感知的方法有很多，协作频谱感知克服了单节点频谱感知的缺点，特别是在衰减信道中。(In CR, spectrum sensing has many methods. The collaborative sensing is better than the single sensor sensing as a result of making the fading.)

matlab环境下计算MFCC参数（mel倒谱参数），lpcc参数（线性预测倒谱）和pitch（基因）(calculate mfcc lpcc pitch )

说明：  本文对指纹特征点的提取，特征点的匹配，用matlab进行了实现(In this paper, the fingerprint feature points extraction, feature point matching, was realized with matlab)

根据电缆长度计算电缆短路电流。写的不是非常好(Calculation of cable short circuit current according to the length of the cable.)

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用周期图法和 ARMA谱估计法(SVD-TLS)估计此信号的功率 谱，并分析比较其结果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try periodogram and ARMA spectral estimation method (SVD-TLS) estimate the power spectrum of this signal, and the analysis and comparison of the results)
