对802.11a物理层进行了仿真，我还没有仔细看，压缩包中有两个文件夹，一个是R13，另一个是R13SP1，好像是用simulink仿真出来的(802.11a physical layer of the simulation, I have not carefully watch, compressed package has two folders, one is R13, the other is R13SP1, seems to be out of use simulink simulation)

Principal component analysis (PCA) is a popular tool for linear dimensionality reduction and feature extraction. Kernel PCA is the nonlinear form of PCA, which is promising in exposing the more complicated correlation between original high-dimensional features. In this paper, we first talk about the basic ideas of PCA and kernel PCA, and then focus on the reconstruction of pre-images for kernel PCA. We also give an introduction on how PCA is used in active shape models (ASMs), and discuss how kernel PCA can be applied to improve traditional ASMs. Then we show some experiment results to compare the performance of kernel PCA and traditional PCA for pattern classification. We also implement the kernel PCA-based ASMs, and use it to construct human face models.
