经验模态分解的matlab源程序，手工编写样条插值方法(Empirical mode decomposition matlab source, manual preparation of spline interpolation method)

说明：  FLAMES平台中的空域模型之一，对空间划分有借鉴意义(FLAMES airspace model in one platform, a reference to the space division)

通信系统的matlab仿真，实现抽样量化、信源编码解码，信道编码解码，调制解调(Matlab simulation of the communication system, sampling quantization, source coding and decoding, channel coding and decoding, modulation and demodulation)

人脸识别方面KDDA算法的matlab实现(face recognition algorithm aspects KDDA achieve Matlab)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)技术以其频谱利用率高和抗频率选择性衰落强等优点，成为下一代移动通信中最具竞争力的关键技术之一(OFDM (Orthogonal Frequency Division Multiplexing, OFDM) technology for its high spectrum efficiency and strong anti-frequency selective fading, etc., to become the next generation of mobile communications in the most competitive one of the key technologies)

说明：  用matlab编写的基于Haar小波变换的图像增强处理，同时可实现小波正变换，小波逆变换，实现小波分解与重构源代码。(Written by matlab Haar wavelet-based image enhancement processing, and can achieve positive wavelet transform, inverse wavelet transform, wavelet decomposition and reconstruction to achieve the source code.)
