AR4JA LDPC Coded Modulation in C and Matlab

The software supports the modulations of binary phase-shift keying (BPSK), quadrature PSK (QPSK), 8-PSK, 16 amplitude PSK (16-APSK), and 32-APSK. For each modulation type, the software modulator support for various bit-to-modulation-symbol mappings, including the natural order, the Gray code, the...

ARAJ Low-Density Parity Check (LDPC) Codes

This software provides a construction method for protograph-based Low Density Parity Check (LDPC) codes that simultaneously achieve low iterative decoding thresholds and linear minimum distance. The technology can be used for various code rates. Proposed codes may have either fixed input block or...

Artwork Separation

Under a grant from California Institute of Technology, Jet Propulsion Laboratory (JPL) and LACMA (Los Angeles County Museum of Art) used image enhancement techniques to separate x-ray images of paintings when one had been painted on top of another. The technique is derived from computer processing...

Astronomy Aid

As a Jet Propulsion Laboratory astronomer, John D. Callahan developed a computer program called Multimission Interactive Planner (MIP) to help astronomers analyze scientific and optical data collected on the Voyager's Grand Tour. The commercial version of the program called XonVu is published by...

Athena

One of the big efforts of NASA is the observation of planet earth from space. Global climate change is a prime example. Extending Athena from the county level to the global level would give a simulation tool for examining how populations and countries might respond to global cllimate change and/or...

Auto Draw From Excel Input Files

The software allows visualization of complex data in a format that is more easily understandable than pages of numbers. Because the graphical output can be updated automatically, the manual labor of diagram drawing can be eliminated. The more frequent update of system diagrams can reduce confusion...
