The implementation of a lossless data compression module in an advanced orbiting system: Analysis and development [PDF]

open access: yes
Data compression has been proposed for several flight missions as a means of either reducing on board mass data storage, increasing science data return through a bandwidth constrained channel, reducing TDRSS access time, or easing ground archival mass ...

Design of source coders and joint source/channel coders for noisy channels [PDF]

open access: yes
A theory behind a proposed joint source/channel coding approach is developed and a variable rate design approach which provides substantial improvement over current joint source/channel coder designs is obtained.

Study of spin-scan imaging for outer planets missions [PDF]

open access: yes
The constraints that are imposed on the Outer Planet Missions (OPM) imager design are of critical importance. Imager system modeling analyses define important parameters and systematic means for trade-offs applied to specific Jupiter orbiter missions ...

An image compression technique for use on token ring networks [PDF]

open access: yes
A low complexity technique for compression of images for transmission over local area networks is presented. The technique uses the synchronous traffic as a side channel for improving the performance of an adaptive differential pulse code modulation ...

Implementation issues in source coding [PDF]

open access: yes
An edge preserving image coding scheme which can be operated in both a lossy and a lossless manner was developed. The technique is an extension of the lossless encoding algorithm developed for the Mars observer spectral data.
