说明：  数字下变频技术是数字接收机的核心技术之一，它包括数字混频正交变换、抽取及高效率数字滤波等。(Digital down conversion technology is one of the core technology of digital receiver, which includes digital mixer orthogonal transformation, extraction and high-efficiency filtering.)

This is a Single Pulse Simulation Block for Power Converters in MATLAB Simulink.

qpsk信号瑞利信道的仿真程序还有搞死的有ber(qpsk signal Rayleigh channel simulation program has also Gaosi ber)

说明：  通过非线性动力学中混沌研究的poincare图可以很方便的识别出周期，拟周期或者混沌运动，该程序实现了poincare图的绘制(Through the study of nonlinear dynamics in the chaotic poincare map can easily identify periodic, quasi-periodic or chaotic motion, the program achieved poincare mapping)

滑移率的模拟,应用simulink实现的程序(simulink of U)

calculates the shortest path and distance between two nodes on a map

MATLAB GUI设计学习手记（第二版）源程序 第3章 本书推荐的学习方法： 1）若您是一个MATLAB初学者，且有充裕的时间来学习GUI设计，您可以从本书的第1章开始循序渐进地学习。 2）若您是一位MATLAB初学者，且时间非常紧迫，建议您先学好第1章，然后依次学习第4章、第5章和第6章，其他章节请根据项目需要有选择性地学习。 3）若您已经掌握了MATLAB的基础语法知识，有一定的MATLAB编程基础，也请浏览一下第1章的内容，尤其是专题分析部分。然后先学习本书第4、5和6章，其他章节请根据项目需要有选择性地学习。 4）若您是一位MATLAB GUI方面的专家或老师，您可以将本书作为一本教学的参考书，本书内容全面、讲解详实、代码精炼，是不可多得的GUI宝典。 (MATLAB GUI design learning Hearts (second edition) source Chapter 3 the learning methods recommended in this book: 1) If you are a MATLAB beginners, and have plenty of time to learn GUI design, you can start from Chapter 1 of the book The step-by-step learning. 2) If you are a MATLAB beginners, and the time is very tight, it is recommended that you first learn to Chapter 1, followed by learning Chapter 4, Chapter 5 and Chapter 6, in other sections based on project needs selective learning . 3) If you have mastered the basic grammar of the MATLAB, the MATLAB Programming Fundamentals, please visit the Chapter 1, in particular thematic analysis section. First learning book chapters 4, 5 and 6, then the other chapters selective learning based on project needs. 4) If you are an expert or teacher of a MATLAB GUI, you can book as a teaching reference books, the book is comprehensive, explain the detailed, refined code, is a rare GUI canon.)
