说明：  《数字通信（第四版）》答案 《数字通信》(第4版)是数字通信领域的一本经典教材,通过对概率论及随机过程的复习,详细介绍了数字和模拟信源编码、数字调制信号和窄带信号与系统的特征、加性高斯白噪声中数字通信的调制和最佳调制与检测方法、基于最大似然准则的载波相位估计和定时同步的方法、不同信道模型的信道容量及随机编码、带限信道的信号设计、受到符号间干扰恶化信号的解调与检测问题、自适应信道均衡、多信道与多载波调制、扩展频谱信号和系统、衰落信道上的数字通信。(The solution of "Digital communication" " Digital communication" (4th edition) is a digital communications of a classic textbook in the field, through the review process, the probability of randomly addressed, details of the digital and analog source coding, digital modulation signal and the narrowband signal and system characteristics, additive white Gaussian noise in digital communication modulation and the best modulation and detection methods, based on maximum likelihood criterion of carrier phase estimation and time synchronization method, different channel model of channel capacity and random coding, band-limited channel signal design by ISI worse signal demodulation and detection, adaptive channel equalization, multi-channel and multi-carrier modulation, spread spectrum signals and systems, fading channel digital communications.)

可以读取obj格式的文件到matlab空间中，obj格式的文件中，只能包含点和面的信息(Obj file format can be read into matlab space, obj file format, can contain only the information points and surfaces)

傅科摆的matlab模拟程序，有考虑一次阻力，二次阻力。同时有一个word描述。学习matlab ode的好代码(Foucault pendulum matlab simulation program, considered a resistance, secondary resistance. At the same time there is a word description. Code of good learning matlab ode)

基于遗传算法的TSP算法的Matlab程序实现(Matlab program TSP algorithm based on genetic algorithm to achieve)

带有Python界面的EMDEEMDCEEMDAN的程序，做信号处理。(libeemd is a C library for performing the ensemble empirical mode decomposition (EEMD), its complete variant (CEEMDAN) or the regular empirical mode decomposition (EMD). It includes a Python interface called pyeemd. The details of what libeemd actually computes are available as a separate article, which you should read if you are unsure about what EMD, EEMD and CEEMDAN are.)

说明：  第二种孤岛运行的控制是采用下垂控制（droop控制），Droop控制就是用来模拟频率一次调整。通过控制电力电子逆变器来实现。(The second kind of island operation control is droop control, Droop control is used to simulate a frequency adjustment. It is realized by controlling the power electronic inverters.)

正余弦信号的谱分析 数字信号处理方法的一个重要用途是在离散时间域中确定一个连续时间信号的频谱，通常称为频谱分析，(Cosine signals are digital signal processing method of spectrum analysis is an important use is in the discrete time domain to determine a continuous-time signal spectrum, commonly referred to as spectrum analysis,)
