水下多目标检测算法（AIC）——matlab程序 detection_AIC.rar (2 K) 很简单的一个算法程序，初学者进来看看。(Underwater multi-target detection algorithm (AIC)- matlab program detection_AIC.rar (2 K) of an algorithm is very simple procedure, come take a look at beginners.)

BOC 信号 生成方法 自相关函数 频率功率谱密度 BOC 信号 生成方法 自相关函数 频率功率谱密度(BOC signal, the autocorrelation function, the frequency spectrum analysis.)

说明：  实指数序列a=1/2 实指数序列a=1/2(Real exponential sequence a = 1/2)

说明：  模糊c均值（fcm）实现无监督聚类算法，经本人尝试，程序可以正常运行(Fuzzy C-means (FCM) to achieve unsupervised clustering algorithm, I try, the program can run normally)

pwm整流器的建模仿真，主要为数据分析和统计，实现串口的数据采集。( Modeling and simulation pwm rectifier Mainly for data analysis and statistics, Achieve serial data acquisition.)

说明：  副瓣对消，采用主波束采样数据与对消波束数据的相关性，进行对消(use main beam and cancellation beam to eliminate sidelobe targets)

利用MATLAB实现PSK系统的仿真 很实用(PSK systems using MATLAB simulation to achieve practical)

数字基带系统将数字信号从时域上看时数字滚降，需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。 采样判决后的码型。 2、眼图（采样判决之前的眼图）（信噪比大眼图清晰） 3、误码曲线，（横坐标时信噪比，纵坐标时误码率） 4、Arfa变化对误码特性的影响，变好还是变差(变好)，眼图清晰度变化（清晰），传递函数的带宽的变化。（带宽越大）(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum. Sampling pattern after the verdict. 2, the eye diagram (eye before sampling decision) (SNR big eye clear) 3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis) 4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

连杆机构的运动分析，曲柄滑块机构的运动学分析(Analysis of the kinematics of the slider-crank mechanism)

对图像分割，初始轮廓为椭圆。变化的过程中始终以椭圆为约束(For image segmentation, the initial contour is an ellipse.)
