16 qadrature amplitude modulation convert 4bits to its reall and imajenary points

TDOA定位定位Chan算法,CHAN算法,假设移动台与各基站位置较近,需进行三四WLS计算 输入参数: R(N-1×1): TDOA测量值 Pbs(N×2): 基站的坐标,第一列为X,第二列为Y 参考基站坐标位于第一行 输出参数: POS_ref(2X1):第一次WLS的估计结果,作为参考作最终定位结果的判决 POS1(2X1) :定位结果1 POS2(2X1) :定位结果2 POS3(2X1) :定位结果3 POS4(2X1) :定位结果4(TDOA Location positioning Chan algorithm)

apriori算法，用MATLAB写的。 不是本人所写，但感觉写得不错，特与大家分享 (I have not written, but the feeling is well written, special to share with you)

数字波束形成，阵列信号，里面包含了经典DBF算法和基于FFT多波束形成算法，适合初学者，自己编的(Digital beamforming, array signal, suitable for beginners, own)

In a series of papers in recent years new structures for coherent M-PSK (M-ary Phase Shift Keying) receivers were suggested. These include structures for carrier phase detectors for the carrier PLL (Phase Lock Loop), carrier PLL lock detectors, symbol timing error detectors, symbol synchronization PLL lock detectors, carrier and symbol PLL loop filters, and SNR (Signal to Noise Ratio) estimators

本程序是一个相对完整的matlab simulink 光伏发电系统的仿真，MPPT运行了扰动法，可以为有相关需要的同学提供一定的借鉴。(This program is a relatively complete simulation of MATLAB Simulink photovoltaic power generation system. MPPT runs the perturbation method, which can provide some reference for students who need it.)

Signal & Systems WITH MATLAB e-book good for signal & system engineering course

说明：  地震处理 叠后F-K偏移 有差值方法选择等(FK migration in the post-stack seismic processing)

AC and DC speed control system simulation

高斯低通/高通频率域滤波实现图像的模糊/锐化(Gaussian low pass/high-pass filtering in frequency domain image of the fuzzy/unsharp)
