EVALUATION OF A BURST-ERROR CORRECTION CODE ON A GILBERT CHANNEL
ROME AIR DEVELOPMENT CENTER GRIFFISS AFB NY
Pagination or Media Count:
Error correction codes have been designed to allow the communication engineer to add a degree of error protection to transmitted digital data. Difficulties arise, however, when it is desired to obtain maximum efficiency from the redundant digits added to a particular channel. A technique for evaluating the improvement afforded a fading-type channel by the use of a burst- error correcting code is illustrated. The Gilbert model of a fading channel is then evaluated using this technique. A series of curves are present showing the improvement in error rate afforded this particular channel by a burst-error correction code as a function of the reduced information rate.
