说明：  多进制数字相位调制也称多元调相或多相制。它利用具有多个相位状态的正弦波来代表多组进制信息码元,即用载波的个相位对应于组进制信息码元。如果载波有2k个相位，它可以代表k位进制码元的不同码组。多进制相移键控也分为多进制绝对相移键控和多进制相对(差分)相移键控。(This m-file simulates mpsk (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).)

针对系统的射频隐身性能评估问题，首先提出了射频隐身的评估指标体系并对指标进行归一化模糊处理;然后，利用层次分析法确定了各指标的权重，并建立了三级评估模型，实现了射频隐身性能的量化评估;最后，对两种系统的射频隐身性能进行了模糊综合评估(According to the problem of RF stealth efficiency evaluation,the evaluation index system of RF stealth is presented and normalized by the fuzzy translation.)

说明：  双站测角GDOP仿真，有原理、推导公式、matlab仿真都有(Dual station angle measurement GDOP simulation, principle, derivation formula, matlab simulation)

说明：  正交频分复用频谱生成程序，以及其结果图。(Orthogonal frequency division multiplexing spectrum generating program and its result chart.)

说明：  本书是《算法艺术与信息学竞赛》的学习指导。所谓学习指导，是告诉读者学什 么，如何学。算法包罗万象，很难在一本书中的篇幅覆盖很多内容的通知对每个知识 点进行细致讲解，因此本书更多的是作为一本导引、工具书、手册或者学习大纲，给 读者以宏观上的学习指导(This book is a study guide for the Competition of Algorithmic Arts and Informatics. The so-called learning guidance is to tell readers what to learn and how to learn. Algorithms are all-inclusive, and it is difficult to explain each knowledge point in detail with a notice covering a lot of content in a book. Therefore, this book is more used as a guide, a reference book, a handbook or a learning outline to give readers macro-learning guidance.)

说明：  51单片机8位xpt2046芯片对电位器的模数转换(Analog-to-digital conversion of 51 single-chip 8-bit xpt2046 chip to potentiometer)

可把一块图片分割几部份，切片数量可由用户定制，游戏开始后顺序打乱，然后让你拼图。(A picture can be split into several parts, cut the number of user customization, upset the order after the start of the game, and then let you puzzle.)

wpf的hello world程序，就是测试使用的。使用了vs 2017编译的。(a test program for c#)
