基于MATLAB的语音信号处理，实现对语音信号的时频分析，加噪滤波处理等等(Speech signal processing)

New Bases for OFDM system subcariers and its destribution in wigner

This is My Kalman Filter

This is an implementation of the algorithm described in our paper [1]. The input is any map generated by saliency detection algorithms like Itti-Koch [2] or GBVS [3]. The algorithm outputs a binary mask without requiring a threshold for the saliency map. More details about it are described in our paper.

说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)

说明：  一种新型的算法，将模拟退火法和遗传算法相结合，用于求解预测问题(A new algorithm, simulated annealing and genetic algorithm are combined to solve the prediction problem for)

说明：  实现random forest,一种较新的，有效地分类算法(random forest classification)

matlab 画3d的心形图。用matlab实现。(matlab draw 3d heart-shaped figure. Using matlab.)

This program is used to Calculate z transform, s transform..etc
