中文说明：结合PCA的尺度不变特征变换(SIFT)算法，基于人工神经网络的常用数字信号调制，采用热核构造权重，课程设计时编写的matlab程序代码，借鉴了主成分分析算法（PCA），采用加权网络中节点强度和权重都是幂率分布的模型。
English Description：
Combined with PCA scale invariant feature transform (SIFT) algorithm, commonly used digital signal modulation based on artificial neural network, the thermonuclear structure weight, matlab code written curriculum design, drawing on the principal component analysis (PCA) algorithm, the weighted network node strength and weight are power-law distribution model.
