说明：  一些有关SIFT衍生算法的资料，包括ASIFT, CSIFT, PCA-SIFT, SURF算法，中英文都有，很有价值(Some of the SIFT algorithm is derived, including ASIFT, CSIFT, PCA-SIFT, SURF algorithm, in each category, great value)

3G物理层调制和解调的演示仿真模型。 A simulation of physical layer of 3G communication system.(3G physical layer modulation and demodulation of the display simulation model. A simulation of physical layer of 3G communicat ion system.)

中频70M，30M带宽LFM信号，采样率为102.4M，数字下变频后，还进行了三倍抽取，最后还得到I，Q两路信号 (IF 70M, 30M bandwidth LFM signal, the sampling rate of 102.4M, digital down conversion, the samples were carried out three times, the last also I, Q two-way signal)

经验模态分解的程序，由其他学者提供，使用方便高效。(emd programme)

this helps for range filtering

说明：  现代通信原理作业。窄带调频和窄带调相的方法来进行窄带角调制，还有ssb，vsb和pm调制的代码。(Modern communication principle operation. Narrowband modulation and narrowband phase modulation for narrowband angle modulation)

本程序为matlab程序关于模式识别的LMSE算法的简单应用，比较适合初学者使用(This program is about pattern recognition matlab program LMSE algorithm simple application, suitable for beginners to use)

很标准的无味卡尔曼滤波，UKF的仿真与用法。描述了两个非线性方程x=0.5 x + (25 * x / (1 + x^2)) + 8 * cos(1.2*(t-1)) y = (x^2 / 20)的UKF的用法。简单实用，有备注。对于卡尔曼滤波初学者很有用。(Very standard unscented Kalman filter, UKF simulation and usage. Describes two nonlinear equations x = 0.5 x+ (25* x/(1+ x ^ 2))+ 8* cos (1.2* (t-1)) y = (x ^ 2/20) of UKF usage. Simple and practical notes. For the Kalman filter useful for beginners.)

有12个外表一模一样的小球，其中有一个的质量和其他11个球不一样（11个球的质量完全相同） 而且该球不知道是轻点还是重点。现在给你一个天平（无砝码），只有3次测量机会，请你找出该球。(12 looks exactly the same ball, which has a quality and not the same as the other 11 balls (11 balls in the quality of the identical) and that the ball does not know the point or focus light. Now to give you a balance (no weight), only 3 measurements chance, you find the ball.)
