自己收集的一点资料，特别是如何在matlab中实现滤波器设计(Own collection of little information, especially how to implement filter design matlab)

这个是关于无线射频识别室内定位系统的编程框架，如果你想学习室内定位系统的编程，可以参考这个，可能会给你启发(This is about the RFID indoor positioning system, programming framework, if you want to learn programming indoor positioning system, can refer to this, it might give you inspiration)

说明：  DSP入门：数字滤波器设计(双线性变换法)(DSP basis: Design of digital filter(Double linear transform))

说明：  本书是学习数值方法最新版本matlab实现的好帮手，详细而全的讲解及实现为自学matlab是一本不错的书籍。(This book is the latest version of matlab numerical methods to learn to achieve a good helper, detailed and full realization of the self-presentation as well as matlab is a good book.)

离散傅里叶变换的子程序，matlab的built in函数的一部分程序(Discrete Fourier Transform subroutine built in matlab function part of the program)

本书提供了matlab语言的编程语法和基本函数，并给出了simulink仿真实例，对于学习matlab的人来说非常有用(This book provides a matlab programming language syntax and basic functions, and gives simulink simulation for learning matlab very useful for people who)
