this matlab code for Image contrast enhancements of grey and rgb images.

冈萨雷斯数字图像处理的所有matlab源码，非常全的一个，供大家对着课本学习使用。强烈推荐给大家。那本书也写的非常不错。(Gonzalez digital image processing matlab source code for all, a very wide one, for everyone to learn to use against the textbook. Strongly recommend to everyone. That book also write very good.)

FSK编码器和译码器,有需要的朋友可以看看！(FSK encoder and decoder, there is a need friends can see!)

源代码为matlab函数，功能是根据副瓣抑制要求产生taylor权系数(failed to translate)

说明：  We describe a new method for performing a nonlinear form of Principal Component Anal

本文在介绍MIMO无线通信系统模型的基础上，通过对比分析几种常用空时编码方法，选定空时分组码对信号进行编码并建立瑞利衰落信道模型，通过对两发一收及两发两收系统的仿真，研究接收天线数对系统接收信号可靠性的影响。之后进一步扩展到不同发射矩阵条件下研究多发一收系统的频谱利用率及误符号率，分析不同天线数目，不同发射矩阵条件下空时正交分组码检测算法的性能。(This paper introduced the MIMO wireless communication system model, through the comparative analysis of several commonly used method of space-time coding, grouping code for the selected space-time signal is encoded and establish Rayleigh fading channel model, through two rounds one and two rounds of closing Simulation of two closed systems, research receiving antennas to receive signals affect the reliability of the system. After further extended to study the conditions under different emission matrix of multiple spectral efficiency and symbol error rate of a closed system, analyze the different number of antennas, the performance under different emission matrix orthogonal space-time block codes condition detection algorithm.)

这是周建兴的《matlab从入门到精通》第5章的所有源代码，都可以运行的出来，和课本上的一样，(This is Zhoujian Xing' s " matlab from entry to the proficient," Chapter 5, all the source code, you can run out, and textbooks on the same)

一个用fortran90写成的BVP（ODE）的求解器，作者是写matlab函数bvp4c的作者。原理差不多。不过这个版本是用f90写的，运算速度更快。本包内含如何运这些程序的论文及算例，很好上手。(In the declarations part of this module, we first define the BVP_SOL type, which represents the numerical solution. We next define the interface BVP_INIT, which is overloaded to provide a number of functions for allowing the user to specify initial information for the computation, the interface BVP_EXTEND, which is overloaded to provide functions for extending the numerical solution to a new domain that are useful in the context of parameter continuation, and the interface BVP_EVAL, which is overloaded to provide a function for retrieving solution information. Next a number of global variables employed throughout the code are defined. )

该代码通过对常规单脉冲雷达信号、LFM雷达信号和BPSK雷达信号通过wiger变换，得到三种信号的时频图，分析他们的时频关系和区别。(The code on conventional single-pulse radar signals, LFM radar signals and radar signals BPSK wiger transformation, three kinds of time-frequency map analysis of their relationship and when the frequency difference.)
