Automatic Repeat Query (ARQ), Forward Error Corrector (FEC), and hybrid protection systems
Abstract
System performance criteria for error protection are reviewed and different error detection techniques are considered. Various forward error corrector (FEC) decoding systems and automatic repeat query (ARQ) coding systems are discussed. Coding systems in satellite communications are characterized. The implementation of FEC coding in time division multiple access is described. Communication efficiency is shown to be suitable and the impact on ground stations is explained.
