FEEDBACK DECODERS FOR NAVAL APPLICATIONS

International Telemetering Conference Proceedings / October 10-12, 1972 / International Hotel, Los Angeles, CaliforniaFeedback decoding is a simple technique for obtaining a significant improvement in performance on a wide range of binary channels. Code interleaving for burst error correction is particularly simple to implement with feedback decoding. A flexible feedback decoder built by LINKABIT Corporation was tested on a simulated shipboard satellite communication channel. The channel was characterized as being additive Gaussian with a superimposed 5% duty factor periodic burst during which the channel error rate is close to .5. The precise radar induced error burst locations are assumed unknown to the decoder. The simple feedback decoder, operated with the error bursts,provided performance equivalent to t at of an uncoded system operating against additive Gaussian noise alone.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
