信号稀疏表示是一种新兴的信号分析和综合方法,其目的就是在过完备字典中用尽可能少的原子来表示信号。采用时频原子字典的信号稀疏表示能够有效地揭示非平稳信号的时变特征。信号稀疏表示吸引了研究者的大量关注,这种方法已经被应用到信号处理的许多方面,例如非平稳信号分析,信号编码、识别与信号去噪等。(Signal sparse representation is a new method of signal analysis and synthesis, and its purpose is in over-complete dictionary of atoms using as little as possible to represent the signal. When using frequency atom dictionary signal sparse representation can effectively reveal the time-varying characteristics of non-stationary signals. Signal sparse representation attracted a lot of attention of researchers, this method has been applied to many aspects of signal processing, such as non-stationary signal analysis, signal encoding, recognition and signal denoising.)

FFT
脑波FFT变换
调用格式见m文件头部说明(下边也复制了一份)
有配套.DLL.h.lib.ctf文件,可以在C或C++环境中调用
------------------------------------
保存为FFT.m文件
输入参数: N:进行FFT变换的点数(要求是2的N次幂);
fs:信号的采样频率(frequency of simpling)
sig:进行FFT变换的数组(一维)。
输出参数: f_sig:变换后的信号(一维数组)
E_delta、E_theta 、E_alpha、E_beta分别表示δθαβ相应频段的能量加和。
other为其余频段的能量加和(供参考用)
--------------------------------------------------------------------------
function[ f_sig ,E_delta , E_theta , E_alpha , E_beta , other ] = FFT( N , fs , sig )(EEG FFT transform is called m file format, see head illustrate the matching DLL files, you can be C or C++ to call------------------------ simpling) sig: to FFT transform array (one dimension). Output Parameters: f_sig: transformation of the signal (one-dimensional array) E_delta, E_theta, E_alpha, E_beta δθαβ, respectively, the energy increases and the corresponding frequency band. Other for the rest of the energy band increases, and (for reference) -------------------------------------------------------------------------- function [f_sig, E_delta, E_theta, E_alpha, E_beta , other] = FFT (N, fs, sig))
