Error correcting coding for satellite communications

This report describes the most relevant block- and convolutional codes to be used in satellite communication systems. Design trade-offs are given for the choice of coding techniques in SCPC, TDMA and SS-TDMA communication system,

Channel coding with the (255,255-2T) Reed-Solomon codes over CF(256)

The class of (255, 255-2T) Reed-Solomon codes over CF(256) is studied in detail. In particular the encoding and decoding algorithms are elaborated. Main computational elements are the discrete Fourier transform for syndrome and error locator computation, Euclid's algorithm for solving the key equation and Horner's scheme for determining the...

Image data security in the concept of the agricultural real time imaging satellite system (artiss)

The study on image data security is directed to the requirement for exclusive access to satellite imagery in the concept of the Agricultiiral Real Time Imaging Satellite System (ARTISS). The security assessment indicates that user survey requests are handled confidentially and it shows the access vulnerability of the transmission of image data...
