System-Identifiation

我自己写的OFDM的一些仿真程序，时域图、频域图以及一些错误图样等。(I wrote it myself a number of OFDM simulation program, time-domain diagrams, frequency-domain maps and drawings and so some errors.)

基于PCA的人脸特征抽取，首先将200幅人脸图像转换成向量形式，进而进行组成样本矩阵。(The PCA-based facial feature extraction, first 200 face images into a vector format, then the composition of the sample matrix.)

数字水印源码，基于matlab的，可实现，共同分享。(Digital watermarking source code, based on the matlab can be realized.)

In this File, performance evaluation of 4-QAM system in the presence of Automatic Gain Control (AGC) errors using MATLAB Software. The system is designed, modeled and simulated using Simulink to evaluate the Bit Error Rate (BER) of the system in AWGN channel. The system doesn’t have a perfect AGC, but for comparison purposes, the perfect AGC is also included and evaluated.

OFDM 通信信道设计,主要是关于无线移动通信中Jakes 模型进行信道仿真和相应的改进算法。(OFDM communication channel system design)

benchmark.zip主要包含一些标准的通用的优化算法的测试函数，共有17个。(benchmark.zip mainly contains some standard test function optimization algorithm, a total of 17.)

核局部邻域嵌入算法是一类流形学习算法，可用于数据的降维(Kernel local neighborhood embedding algorithm is a manifold learning algorithm, which can be used to reduce the dimensionality of data)

球面网格点判断，找到合适的三角点，不成熟，请见谅。(spherical grid judgment, to find a suitable Triangle, immature, and I do apologize.)
