a frequency modulation code for matlab

说明：  matlab实现的arnold置乱变换,很好用(matlab implementation arnold scrambling transformation, useful)

matlab程序，气象学上画风场，可以添加标尺(matlab procedures, meteorology style games, you can add the ruler)

说明：  6RPS工作空间绘制求解matlab程序(6rps workspace solution)

这可是我两年前用matlab写的第一个函数，算是处女作。 这个例子涉及三角函数的系数变换及其极坐标系绘图，以及界面和控件的颜色修改。(But I used it two years ago to write the first matlab function can be regarded as a debut. This example involves the coefficient of trigonometric function transform and its polar coordinates drawings, as well as the interface and control color modify.)

时隙ALOHA协议是对ALOHA协议的简单修改，把传输时间分为一个个时隙，数据包只能在时隙的开始进行并行传输。在当前的时隙中产生的数据包只能在下一个时隙的开始进行并行传输。(Time slot ALOHA protocol is simple modification of ALOHA protocol, the transmission time is divided into a time slot, packets can only be the beginning of time slot for parallel transmission. In the current time slot of packets can only be the beginning of the next time slot for parallel transmission. )

本论文首先介绍了当前深空通信的编码调制技术的现状与发展，阐述了以往 的深空通信中的编码和调制技术的方案和局限性，提出LDPC码和FQPSK调制的 优越性和发展前景。第二章描绘了LDPC码的奇偶校验矩阵的图形表示、生成方 式和译码方法，并比较二元LDPC码和多元LDPC码的优越性和实现问题。第三 章在介绍FQPSK调制的方案的由来、改进和发展的基础上，对其进行了功率谱分 析，介绍了一些常规的解调方案。(This paper introduces the current situation and development of the technology of deep-space communication code modulation on the coding and modulation techniques in deep space communications program and limitations of the proposed of LDPC codes FQPSK modulation superiority and development prospects. Chapter II depicts a graphical representation of the LDPC code of the parity check matrix generation method and decoding method, and compare the superiority of binary LDPC codes and multiple LDPC code and implementation problems. Chapter origin in the introduction FQPSK modulation program, improvement and development on the basis of its power spectrum analysis, conventional demodulation.)
