采用的是RD算法实现合成孔径雷达成像，距离－多普勒RDA二维成像仿真(RD algorithm is used in synthetic aperture radar imaging, range- Doppler two-dimensional imaging simulation RDA)

UPSAMPLING AND DOWNSAMPLING

自适应学习字典代码：训练字典的MATLAB仿真程序，能够很好的认识字典训练事例 (Adaptive learning dictionary code: dictionary MATLAB simulation training, can very good dictionary training examples )

利用GUI设计要求的用户界面。该界面包括一个轴对象，显示的图形包括表面图、网格图和等高线图。(Use GUI design requirements of the user interface. The interface consists of an axis object display graphics include surface maps, grids and contour map.)

　支持向量机方法是建立在统计学习理论的VC 维理论和结构风险最小原理基础上的，根据有限的样本信息在模型的复杂性（即对特定训练样本的学习精度，Accuracy）和学习能力（即无错误地识别任意样本的能力）之间寻求最佳折衷，以期获得最好的推广能力[14]（或称泛化能力）。 (SVM is based on statistical learning theory and the theory of VC dimension based on structural risk minimization principle, according to the limited sample of information in the model complexity (ie, training samples of a specific learning accuracy, Accuracy) and learning ability (ie, error-free samples to identify any capacity) to find the best compromise between, in order to obtain the best generalization ability [14] (or generalization).)

使用matlab语言进行计算机仿真，仿真bpsk信号的最佳接收和调制。(Computer simulation using matlab language, simulation bpsk the best reception and signal modulation.)

说明：  基于MATLAB的FFT变换， 可用于OFDM信道中(MATLAB' s FFT-based transform, can be used for OFDM channel)

this simulation is a way for watermarking and steganography with HUGO

说明：  有关于光学的MATLAB程序仿真，关于衍射，折射等光学现象(The optical MATLAB example can be used by beginners)

说明：  通用viterbi译码程序,通过改变不同的参数（比如回朔深度），可以进行不同的viterbi译码，(viterbi decode )
