应用傅里叶变换DFT，分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数，所以离散周期信号的频谱 是一个周期的周期性离散频谱，各谱线之间的间隔为 ，而且存在着谐波的关系。 (DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.)

说明：  针对Z变换法无法求取相邻采样点之间的输出响应的局限，利用MATLAB程 序语言，对单位负反馈系统的改进z变换法进行了程序设计。通过simulink仿真的实验，证 明该程序运算快速、准确，使用方便。(For the Z transform method can not strike between adjacent sampling points in response to the limitations of the output, using MATLAB programming language, a negative feedback system of units of the z transform method to improve the program design. Through simulink simulation experiments show that the procedures for computing fast, accurate and easy to use.)

This is a small code for the generation of OFDM signal carriers and encoding data in it. Also sidelobes are suppressed.

Adaboost是一种迭代算法，其核心思想是针对同一个训练集训练不同的分类器(弱分类器)，然后把这些弱分类器集合起来，构成一个更强的最终分类器（强分类器）。 load clouds [test_targets, E] = lijsada_boost(patterns, targets, patterns, 100, Stumps ,[]) train_patterns 每列为一样本 train_targets 每列为一样本目标 100 :Number Of Iterations Stumps: Weak Learner Type Learner s parameters :[] adaboost +stumps testRightR = 0.7522(Adaboost is an iterative algorithm)
