ni5641r模拟输入代码，并画功率谱估计。(ni5641r analog input,and draw power spectrum estimation.)

极化SAR定标处理matlab程序，采用Quegan算法(Polarization SAR processing matlab calibration procedures, the use of Quegan algorithm)

说明：  主要介绍了准正交空时分组码，包括ABBA，jafarkhani(Introduced quasi-orthogonal space-time block codes, including ABBA, jafarkhani)

说明：  matlab写的图像匹配算法 十分有效可用 值得学习！(matlab write very effective image matching algorithm can be worth learning!)

说明：  滤波器设计的目的是对信号进行数据序列的频率变换，去掉其中我们不需要的频率成分，用数字滤波器课实现语音信号去噪(Filter is designed to sequence the signal frequency of the data transformation, which we do not need to remove frequency components, with digital filter class voice signal denoising)

用最速下降法求解无约束非线性规划问题,最大奇异值,其梯度列向量(Using the steepest descent method solving unconstrained nonlinear programming problem)

LBG算法是一种经典的矢量量化聚类算法，本程序用MATLAB实现，方便仿真。(LBG algorithm with MATLAB)
