sharpness，在响度基础上该程序用来计算声音中的响度尖锐度成分(we can use this code calibrate loudness and sharpness in the sound)

研究分析ECG数据的一本书，找了很久才找到的.(This book is intended for graduate students collecting and/or analyzing electrocardiogram (ECG) data, industrial researchers looking to develop, test, and apply new ECG analysis tools (both hardware and software), or simply students or teachers looking for signal processing examples involving an intuitive yet complex signal.)

时间序列自回归分析的matlab代码，根据之前的数据来预测后面数据的变化趋势。(Autoregressive time series analysis of matlab code, to predict the variation tendency of the back data according to the data before.)

预失真器simulink 仿真程序。有输入输出频谱和失真频谱效果图。(Predistorter simulink simulation program. Input output spectrum and distortion spectrum renderings.)

利用傅里叶变换的方法，求含有噪声的两个序列的互相关函数(a method of getting cross correlation function)

包括最小二乘法、SVM、神经网络、1_k近邻法,从先验概率中采样，计算权重，使用matlab实现智能预测控制算法。( Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Sampling a priori probability, calculate the weight, Use matlab intelligent predictive control algorithm.)

Many-featured, platform independent file and directory picker

有关于OFDM在不同信噪比下的误比特率，大家可以看看啊(on OFDM different signal-to-noise ratio in the bit error rate, we can see ah)

说明：  PLL Phase Noise MATLAB simulation

4) 创建一个名为Complex的类，进行复数的算术运算。复数的形式为： realpart+imaginarypart*i 用浮点变量表示类的private数据。提供构造函数，能够对所声明的该类对象进行初始化。在不提供初始化值的情况下，该构造函数应包含默认值。针对以下功能，分别提供一个public成员函数。 （1）两个复数相加； （2）两个复数相减 （3）用（a, b）的形式打印复数，其中a为实部，b为虚部。 (4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)
