通过使用掩码计算梯度（sqrt（R & # 178 +我# 178）。

说明：  本书旨在介绍小波变换，福利叶变换基本理论。小波变换在工程应用中很广泛，比如信号处理，图像处理等。(This book aims to introduce the wavelet transform, the basic theory of Fourier transform welfare. Wavelet transform in a very wide range of engineering applications, such as signal processing, image processing.)

给予QPSK调制的awgn信道调制与解调的matlab例程(Give QPSK modulation awgn channel modulation and demodulation matlab routines)

QPSK信号的调制解调过程，内容包括带通滤波，脉冲成形，以及硬判决译码过程(QPSK modulation and demodulation process of the signal, including a band-pass filtering, pulse shaping, and a hard-decision decoding process)

在DQ轴坐标系下建立了DFIG双馈电机的模型，分为定子和转子两个部分。采用SPWM技术作为输入，磁链和转矩双闭环，实现对转矩的直接控制，转矩直接控制是风力发电中，DFIG双馈电机最常用的方法。
