A statistical language recognition system generally uses shifted delta coefficient (SDC) feature for automatic language recognition. SDCs are stacked version of delta cofficient over several frames. The detail descriptions of SDC and its applications are available in W.M. Campbell, J.P. Campbell, D.A. Reynolds, E. Singer, P.A. Torres-Carrasquillo, Support vector machines for speaker and language recognition, Computer Speech &...
The simulation for educational purposes shows the resulting rotating vector from the 3 by 120 degrees shifted sinusoidals in a phase plane.
This code calculates the cross-correlation for specified time windows over the duration of two input signals. The time windows can be shifted by increments smaller than the time window length. The code is based upon the 'xcorr' function.
This package simulates Q. Zhang's FSR-UWB (Frequency-Shifted Reference Ultra-Wideband) Wireless Communicatons System which is known as the TR-UWB without the delay element.
Use FSRUWBexec.m in order to run your experiments.
sysshift checks whether two matrix M1 and M2 are systematically shifted against each other by calculating correlations across a range of shifted origin. This is helpful e.g. if two different digital elevation models of the same area are to be...
This program returns the coefficients of the shifted Legendre polynomial P_n, given n. The result is a row vector with powers of x decreasing from left to right (standard MATLAB notation). Like for other polynomials, LegendreShiftPoly(n) can be...
This m-file calculates any number of l-moments for given data vector X. It uses probability weighted moments (can actually edit the file to give any number of pwm's) and the coefficients of the shifted Legendre polynomial to calculate the l-moments.
This project has been shifted to Google Code and code commit is stopped here in sourceforge. Visit google code instead for the latest release.
One liner code to shift each char of a string by some passed value very simple encryption :) added version 2 fixing following bugs: 1. Capital chars are shifted correctly. 2. Only alpha numeric chars are shifted. 3. No...
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. ...
Given a 16-element vector which corresponds to the output from a 4-input truth table the k_mapper function returns a 4x4 matrix where all the elements have been shifted to be in the correct order for a 4-input kmap.
I created this...
These are three *very* simple codes for implementing the most rudimentary encryption method possible.
CRYPTOSHIFT.m implements a monoalphabetic shifting substitution encryption. It takes two arguements: the string to be encoded and the...
CXCOV Circular Cross Covariance function estimates. CXCOV(a,b), where a and b represent samples taken over time interval T, which is assumed to be a common period of two corresponding periodic signals.
a and b are supposed to be...
here current error is converter to hexagonal band. inner & outer band corresponds to medium & large vector. here voltage vectors are 30 degree shifted to what is have in case of normal space vector
Transmit beamforming (TxBF) is a method of transmitting two or more phase-shifted signals so that they will be in-phase at particular points in space where the transmitter believes the receiver to be, thereby increasing SNR.
This set of files can be used to construct a polyphase filter bank with near perfect reconstruction. The filter bank is implemented using two uniformly modulated DFT filter banks that are frequency shifted by 1/2 channel width. Effectively,...

PLTSTMP adds a timestamp to the bottom of the figure. If it is called from within a function it also adds the name of the calling function.
The timestamp sometimes plots over the x-axis label. To avoid this, the axis can be shifted...
Turn regular images into depressible, pop-up buttons! This script creates the illusion of an elevated image by applying a shadow and shifting the image to the up and left. When the user holds down the mouse, the shadow is deleted, and the image...
JChart2D is an minimalistic charting library . It is designed for displaying multiple traces consisting of tracepoints. JChart2D is centered around a single configureable swing widget: the Chart2D. It is a JComponent one can add to a java swing... |
