inverse updaing source code in matlab

OFDM信号的编码译码仿真，英文说明更详细。(This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. Note: The both the receiver and transmitter must have a copy of the input data file, as this is used for calculating the exact number of data words in the transmission. The scripts should work as extracted. Just run imagetx.m to generate the OFDM signal. Then run imagerx.m to decode the signal. The initial settings transmit a wave file Corrs.wav . The decoded OFDM data ( Out.wav ) can be compared with the original data by listening to the two wave files.)

说明：  matlab编写的时间序列分析工具，应用AR模型对时间序列进行预测(time series analysis written matlab tools, applications, time series AR model to predict)

独立分量分析的一种快速算法，适合初学者学习。(Independent component analysis of a fast algorithm, suitable for beginners to learn.)

用经典的BJ方法估计ARMA模型，一个经典范例(Using the classical BJ approach to estimate ARMA models, here is an example)

SURF Features A frequent approach to feature extraction from images is SURF (Speeded Up Robust Features) Codebook You can use the function create_codebook.m to create a codebook with k-means Histograms Write a function that creates histograms of single images by assigning the image features to clusters from the codebook and counting their frequency Object recognition Choose two distinct subsets from the images. Create a codebook from one set

Some common algorithms

k—均值分割，分割效果明显，在Matlab下完美实现(K-segmentation, segmentation obviously perfect realization in Matlab)

线性反演方法中的牛顿反演算法 MATLAB程序(MATLAB program for anti-Newton algorithm in the linear inversion method)
