Design of Real-time RS Decoder for Missile-borne Data Link System
摘要
Abstract
To improve transmission reliability, Forward Error Correction ( FEC ) techniques have been widely used in many missile-borne weapon data link systems. Reed-Solomon(RS) code has been proved to be effi-cient for correcting error. Also,its code length can be controlled flexibly,showing great advantage for missile-borne data link system. Three different RS codes are designed to adapt different environment. Furthermore,the widely used Modified Euclidean Algorithm for RS decoding is improved. A novel real-time RS decoder archi-tecture is presented. To attain lower complexity,4 basic calculation cells of decoder are multiplexed internally to solve the error-locator polynomial and error value polynomial. No additional pipeline architecture is inserted. Besides,the complicated inverse operation over GF(28) is completed via Look-up Table(LUT). The whole de-sign has been implemented successfully on EP2S15 FPGA chip of Altera Corp. Compared with existing RS de-coders,the proposed architecture can reduce hardware resources greatly while still meeting required perform-ance. So the presented strategy is much suitable for high-reliability missile data link system design.关键词
