BALLATSQ - Balanced Latin Square M = BALLATSQ(N) creates a balanced latin square of size N containing the numbers 1 to N. N should be an even positive integer. A latin square of size M is a MxM matrix filled with the M different numbers in such a way that each number occurs exactly once in each row and exactly once in each column. A balanced latin square has the further restriction that each sequence of two values in a row...
This function estiamtes the Kolmogorov Complexity of a binary sequence. The algorithm is as described in Lempel and Ziv (IEEE trans inf theory IT-22, 75 (1976)) and Kaspar and Schuster (Physical Review A, vol 36, no 2, pg 842). Input is...
Find sequences of repeated (adjacent/consecutive) numeric values. Finds sequences of NaNs and Infs too.
SYNTAXES: (1) FINDSEQ(A) Find sequences of repeated numeric values in A along the first non-singleton dimension. A shuld be a...
The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is...
This module allows creating multiple repeats/duplicates/clones of nodes based on date sequences. The date sequences are created with the Date Repeat module (part of Date). The nodes must have a CCK Date field, which in the new nodes created by...
Genes4all is a package of modules for visualizing bioinformatic information using GMOD, BioPerl and Chado. It depends on the gmod_dbsf module (http://drupal.org/project/gmod_dbsf) and is in active development. See also...
The PRBS are based on 3 to 9 bits memory delays and put out 2^3 -1 to 2^9 -1 binary sequence length. Usage: these generators can be used in process identification as noise source on command signal
This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is : 1. you can call this function directly in your script, you will have to pass only the value of 'a' (length of...
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...
It is a collection of programs what are made to detect and track bright spot into a image sequence. A manual is added. All of them are written in Spanish.
Often I see students asking for help on a tool to compute the Fibonacci numbers. Or, I'll find them asking for help on a Project Euler problem. Or, a student has been assigned the problem of computing the fibonacci numbers using a recursive...
This is an FSK modulation spread with a PN sequence generator.
It is a simulation file that illustrates the effects of spread spectrum communications.
I am interested on collaboration.
This function reads in a NeuraLynx NVT file (with filename fn) into matlab assuming the format has a 16Kb ascii header and then a repeating binary record given by the following format (variablename, variabletype, number_in_a_row) ...
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...
PythonReports is a toolkit aimed to build database reports in Python programs. The toolkit includes report template designer, report builder and several printout renderers for GUI and graphic file output.
Report builder applies a...
lvbox displays a sequence of images and text applying transition effects between them. Any slide can be an image or a text, and can have an associated link.
Text and image names can be set by using parameters or by writing a text file...
This is a code for simulation of BPSK receiver using Direct Sequence Spread Spectrum. The performnace is evaluated in presence of AWGN and Rayleigh fading. Jakes' Model has been used to obtained coefficients for rayleigh fading.
SPtrack is a GUI (Graphical User Interface) based program written in Matlab which is used for tracking single particles and finding Diffusion properties. It works on Matlab 6 and above platforms and requires the Image Processing Toolbox and the...
This program deals with Spread spectrum communication systems using chaos as the sequence generators.
In coming days I will be updating it with complete chaos based generators Frequency Hopping and CDMA systems with multiple users and...
alculate the normalized partial energy sequence (NPES) for a given signal vector X.
If a particular transform is capable of capturing the key features of a signal in few coefficients, the NPES will approach unity for relatively... |
