P_FUZZY_PID飞行器大角度机动控制物理仿真(Control of Spacecraft Large Angle Maneuvers P_FUZZY_PID Physical Simulation)

说明：  FM调制与解调(MATLAB程序与图) FM也是一种调制方式，即使在短波范围内的27-30MHz之间，做为业余电台、太空、人造卫星通讯应用的波段，也有采用调频（FM）方式的。(FM modulation and demodulation (MATLAB program and map) FM is a modulation, even in the short wavelength range of between 27-30MHz, as amateur radio, space, satellite communications band applications, but also by frequency modulation (FM) way.)

matlab dsp中函数downsample和upsamplec代码(matlab dsp functions in downsample and upsamplec code)

本文利用Matlab对辅助图像处理做了一个全面的介绍，对初学图像处理的朋友很有帮助(It has benefits for learners)

分类器的训练与学习是模式识别的一个重要环节,其目的在于按照某种算法,确定判决规则,使之具有自动分类识别的能力。本文介绍了采用Parzen窗法的随机模式分类器,并matlab实现了一个简易的随机模式分类器。(Classifier training and learning is an important part of pattern recognition, in accordance with the purpose of some kind of algorithm to determine the decision rules to identify with the ability of automatic classification. This paper introduces the Parzen window method using a random pattern classifier, and achieved a simple matlab random pattern classifier.)

跳频信号参数估计。参数为跳速、跳时和跳频频率集。文档包括一个短时傅里叶变换函数，一个参数估计函数，一个参数估计相对误差随SNR的曲线图和一个时频分析图。(Frequency hopping signal parameter estimation.Parameters for speed, to jump and jump frequency set.Document includes a function of the short-time Fourier transform, a parameter estimation function, a parameter to estimate relative error with the SNR curve and a time-frequency analysis diagram.)

说明：  四阶龙格库塔法，在解常微分方程时进行数值求解时调用使用(The fourth-order Runge-Kutta method is used to solve ordinary differential equations numerically.)

轨道FSK信号发送的小函数。这个函数虽然少，但却是在无数可行方案中选的最优，性能最佳的。在这基础上进行信号处理很不错的。(FSK signal sent from the track a small function. This function, though a small, but they are numerous options in the optimal choice, the best performance. In this based on the signal processing is very good.)
