Cubic Spline weight function

这是一个OFDM基于WLAN系统的matlab仿真程序，源代码程序采用了导频符号辅助的OFDM调制机制，采用这种机制对系统误码率进行了仿真。(This is a matlab simulation cede of OFDM based WLAN system used in ETSI BRAN,IEEE 802.11 and ABIB MMAC projects. The program code adopted the pilot symbol-aided OFDM modulation scheme and evaluated the BER performance in the scheme. )

应用KNN算法解决0到9的手写数字识别问题，效果在90 以上，内部有两个数据集，一个为训练集（7291个数据），一个为测试数据（2791个数据），程序采用MATLAB编写，另附有文档，程序简洁易懂(Application KNN algorithm to solve 0-9 handwritten digit recognition problem, the effect is more than 90 , the inside has two data sets, one for the training set (7291 data), a test data (2791 data), the program written using MATLAB , attached a document, the program is simple and easy to understand)

The time is calculated and converted to 64-bit in the first and second lines and then converted to local time zone before being converted to a SYSTEMTIME structure. Last of all the system time is set.

研究生时的现代信号处理的作业，数据模型归一化，模态振动，鲁棒性好，性能优越，数学方法是部分子空间法，使用大量的有限元法求解偏微分方程，搭建OFDM通信系统的框架。(Modern signal processing jobs when the graduate, Normalized data model, modal vibration, Robustness, superior performance, Mathematics is part of the subspace, Using a large number of finite element method to solve partial differential equations, Build a framework OFDM communication system.)

principal component analysis (PCA ) is a well known approach for dimensionality reduction of the feature space. It has been successfully applied in face recognition. The main idea is to decompose face images into a small set of feature images called eigenfaces, which can be considered as points in a linear subspace called “face space” or “eigenspace”
