Abstract：

In　this　paper,　we　propose　a　method　to　reduce　the　number　of　test　patterns　(TPs)　decoded　in　the　Chase　II　algorithm　when　turbo-decoding　product　codes　are　constructed　with　two-error-correcting　extended　Bose-Chaudhuri-Hocqenghem　(eBCH)　codes.　We　classify　TPs　by　their　values　and　the　relationship　of　syndromes,　and　then　reject　those　TPs　that　have　the　same　codeword.　The　method　needs　not　to　check　whether　errors　are　located　at　the　least　reliable　bits　(LRBs)　positions　to　ensure　that　there　are　no　same　codewords　decoded.　For　two-error-correcting　eBCH　(64,51,2),　the　simulation　results　show　that　over　50%　TPs　need　not　be　decoded　for　moderate　signal　to　noise　ratios　(SNRs)　without　any　decoding　performance　loss.
