Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two improved Watterson models and Pseudo- Deterministic model. As a deterministic model, Volger model basically describes the characteristics of HF wideband channel, but it also needs to be improved. The improvement of Vogler model is given in this paper.

本文件是一个SPWM逆变器的仿真源文件，可以在MATLAB7.1中直接运行。设计中PWM Generator采用外部调制信号，并在调制信号中注入了三次谐波，很好的抑制了输出谐波，同时提高了直流电源的利用率。(This document is a SPWM inverter simulation source file, you can directly run MATLAB7.1. Design of PWM Generator external modulation signal, and in the modulation signal into the third harmonic, the output of good harmonic suppression, while improving the utilization of the DC power supply.)

说明：  边缘检测是图形图像处理、计算机视觉和机器视觉中的一个基本工具，通常用于特征提取和特征检测，旨在检测一张数字图像中有明显变化的边缘或者不连续的区域，在一维空间中，类似的操作被称作步长检测（step detection）。(Edge detection is a basic tool in graphics and image processing, computer vision and machine vision. It is usually used for feature extraction and feature detection. It aims to detect the edge or discontinuous area with obvious changes in a digital image. In one-dimensional space, similar operations are called step detection)
