Low Density Parity Check Forward Error Correction for Your Telemetry Link

Abstract

The telemetry standard IRIG 106 includes Low Density Parity Check forward error correction with six combinations of code rate and information block size. This correction code can be added to airborne telemetry links to increase link margin and correct random errors due to transmission anomalies. Given these benefits, why has this technology not been wholeheartedly accepted within the aeronautical mobile telemetry community? This paper will present the trade-offs when considering implementing LDPC in a telemetry link. Real-world flight test results will be presented clearly illustrating the benefits of forward error correction. The data presented will make a strong case for considering IRIG 106 compliant forward error correction in new link designs or to complement existing links in operation today.
