Listing of Communication in Scripts

This GUI has been thought to be a templete for new projects that required signal manipulation. GUI manipulate files. Those files must be created by the digital signal processor, and should contain the signals of the more relevant points of the systems.

  • Platform: Matlab, Scripts

Let us assume the signal model: Y(k)=HX(k)+B(k) This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources.

  • Platform: Matlab, Scripts

Converts binary data of any format in a string to floating point decimal of a defined fraction size. The "intsize" input parameter defines the size of the exponent and sets the fixed point location in the binary number. se accompani for test program for test of this function.

  • Platform: Matlab, Scripts

Let us assume the following MIMO model: Y(k)=HX(k)+Y(k) This file can detect the number of sources, i.e the size of the vector X(k) from the received signal Y(k). The noise is assumed spatially white and the number of receivers must be strictly greater than the number of sources.

This file contain functions to diffraction coeficient for several solid shapes: - absorbig screens; - square wedges; - conductor screens. It provides the coalculation of the tansition function to solve GTD problem with UTD inside transiction zones..

A function that takes two sequences(vectors) as parameters and computes the circular convolution . x(n),h(n) are the vectors. The vectors need NOT be of equal lengths. If they are of unequal lengths, the shorter vector is appended with trailing zeros and then circular convolution is carried out.

  • Platform: Matlab, Scripts

One of the file is a guide to see where the other file should be. The other file return a 60x15 matrix (60 subchannels x 15 OFDMA Symbols) and it is said on that matrix which user has to transmit in each slot. Then we'll have to allocate the information to send it.

IMAGGS(NUM,DEN) Computation of Im[G(s)]=0 of a LTI system with transfer function defined by its NUM, DEN coefficients. Examples used are form "Computation of Stabilizing PI and PID Controllers" by Nusret Tan, Ibrahim Kaya and Dereck P. Atherton. Method is from "Fast calculation of stabilizing PID controllers" by M.

  • Platform: Matlab, Scripts

y = RankOrderFilter(x, window, thd) runs a rank-order filtering of order N on x. y is the same size as x. If x is a matrix, RankOrderFilter operates along the columns of x. Rank-order filter calculates the p'th percentile of the data on an N sized window round each point of x.

This script simulates the Binary Amplitude Shift keying. Since BASK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for 5 bits, so that the results are visible. This is code for BASK only, means it can only modulated two digital states.

  • Platform: Matlab, Scripts

Current direct sequence code division multiple access (DS-CDMA) system suffer from Multiple access interference (MAI) and Inter symbol interference (ISI) due to the frequency selective channel. This interference can be avoided by use of Adaptive Beamforming.

  • Platform: Matlab, Scripts

These m-files are generic implementation of distortion of signals.

JMS Online Support module displays contacts information of your supporter in your site. In the first version, that module only support 5 supporters at the same time and some chat client like yahoo, skype, msn, aim, icq, email, telephone. With the JMS support online module, users in your site can contact with your supporters like customer support, technical support or manager support only by one click.

This program was written as part of a university project. The program uses design curves to allow users to design antennas. The design curves are interactive - i.e., click and drag with the mouse. The accuracy of the design curves is not guaranteed.

This is a collection of m-files I created to complete a research project into the DC components of various encoding techniques. Eight of the files create random bit sequences that conform to their coding requirements. The others were files I found useful in the scope of the project and supplement the g.

Example 1- Input string = 'abc,abc,abc,dcf,dcf,ef'. output string ='3abc,2dcf,1ef' Example 2- Input string = 'xyzr,abdc,abdc,haha,haha'. output string ='1xyzr,2abdc,2haha' Explanation: This function collapses a comma separated long string, containing sub-strings, into a possibly smaller string by replacing repeated sub-strings by counts of repetitions of substrings.

A stack-based sequential priority first decoder that returns Maximum-Likelihood solutions to M-QAM modulated MIMO system-type problems, i.e., a lattice decoder with optional justified rectangular boundary control. In such problems, the depth of the search tree is known and the number of children per node is also fixed.

Hidden Markov models are used to describe the "stepping" behavior of molecular motors, as measured by single-molecule fluorescence techniques. Our HMM implementation is more versatile than the one described by Milescu, et al. Biophys. J. 91:3135-3150 and can be used as a "blind" step detector or to find rate constants and step sizes directly from a measured time course of positions.

Only in very simple situations can we describe the correlation between two time series as a single number. Often it varies both as a function of time, and of wavelength. Datasets may be uncorrelated on short timescales due to noise, but strongly correlated on larger wavelengths (eg annual).

This program places dates on time axis as DATETICK and works with ZOOM and PAN as DATETICKZOOM by Christophe Lauwerys. But, it also shows the full date after zooming or panning by using the ticks and time-axis label. So, if you zoom in down to second, you won't loose "when" you are.
