This function is for training a codebook for vector quantization. The data set is split to two clusters, first, and the mean of each cluster is found (centroids). The disttance of each vector from these centroids is found and each vector is associated with a cluster. The mean of vectors of each...

Although MATLAB is supposed to support both writing and reading data from the serial port, reading data seems to either produce no result, generate an error, or crash MATLAB. To remedy the situation SerialIO() has been written. This function will allow you to set/get vectors of data from the...

This function is a more robust and improved version of my previous submission, matchingpursuit.mThis function computes the projection of a given input vector or matrix onto a "dictionary" of other vectors or matrices using a matching pursuit algorithm. Users may input a vector to be synthesized,...

[FDOUT, FREQ_AXIS] = FDCORR(A,B,FRANGE)FDCORR Joint frequency and delay correlation Performs an efficient circular cross correlation between two vectors over all possible frequency offsets (Dopplers) between -pi and pi where 2pi is the sampling rate.A: vector representing received signal sampled...


Platforms: Matlab

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal).The package also includes two examples. One checks the calculation against the...

This zip file contains two functions: STR2BIN converts an ASCII text string to a vector of binary values, and BIN2STR converts a vector of binary values back to an ASCII text string.


Platforms: Matlab

Matlab source code for the test vectors and Simulink model for physical layer.This model is based on Physical Layer Specification of IEEE 802.16e and ETSI HiperMAN. Run Data.m to copy data to workspace and then run the WiMAX model.


Platforms: Matlab

Dilates a time series input and resizes it to the orignal sample lengthinput. If a matrix is input, dilation is done along columns. % The up/downsampling is done via resample.m, so low-pass filtering of theup/downsampling is automatically implemented. An anti-alaising, lowpassfilter is applied to...


Platforms: Matlab

This function treats a matrix as a column-wise set of signals and circularly shifts each column so that it aligns with the first column of data so that the inner product between those columns is maximized with respect to all other shifts. USAGE:[dataout,lagout]=xcorAlign(data);If only 1 output is...
