velocity_triangulation.zip - Description
This function finds the velocity of a 2-dimensional planar wave from at least 2 sensors, by specifying its location (x,y) or (lon,lat) and its respective arrival time.
It returns the speed and direction (or tracking if coordinates were given):
>> [VEL,DIR] = velocity_triangulation(x,y,time,TOL)
where TOL is a tolerance time. You may get a figure with the results, like the one shown in the screenshot. Just take a look to the optional arguments.
Enjoy it!
Any comments and bugs reports will be very appreciated!

aer_wrappers.zip - These wrapper functions will process standard user inputs and create TAPE5 files and run LBLRTM. This is a lot easier than figuring out what s written in the manual lblrtm_instructions.
LBLRTM stands for Line-by-Line Radiative Transfer model. It is an advanced and highly-configurable radiative transfer model that employs state-of-the art treatment of advanced spectroscopic principles. Go to http://rtweb.aer.com/lblrtm.html
Many thanks to Tony Clough and colleagues who have guided me through running this program.

GioveAB_Orbit_Simulator.zip - The actual version requires the following MATLAB toolboxes:
- Mapping toolbox (for elevation())
- Image Processing Toolbox (for imshow())
A providing of toolbox independent functions would be greatly acknowledged.
You may tweak the sourcecode to adjust the following information:
- Receiver Position
- Receiver Time offset to GMT
- Path of ephemerides file
- Path for satellite track recordings
Ephemerides are taken from
http://www.celestrak.com/NORAD/elements/galileo.txt
and should be updated from time to time
The satellite position calculation (calc_satposition_ecef.m) is based on a program from the Institute of Systems Optimization (ITE) at the University of Karlsruhe, Germany (http://www.ite.uni-karlsruhe.de/). ,2010-03-02 02:18:12,下载20次
symMat.zip - A matrix of symbolic elements is reasonably useful for many analytic linear algebra applications, and for analytic vector, matrix and tensor differentiation.
This function produces a matrix of arbitrary dimension of symbolic elements that are indexed by their position in the symbolic matrix for ease of reference.
EXAMPLE
>> M = symMat([2 2], m , real )
M =
[ m11, m12]
[ m21, m22]
>> class(M)
ans =
sym
>> det(M)
ans =
m11*m22 - m12*m21,2010-03-02 02:13:12,下载7次
LDPC_BSN.zip - LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.
