In　this　paper,　we　propose　a　Distributed　Turbo　Product　Code　(DTPC)　over　cooperative　network　using　block　Bose　Chaudhuri　Hochquenghem　(BCH)　codes　as　component　codes.　The　source　broadcasts　extended　BCH　coded　frames　to　the　destination　and　nearby　relays.　After　decoding　the　received　sequences,　each　relay　constructs　a　product　code　by　arranging　the　corrected　bit　sequences　in　rows　and　re-encoding　them　vertically　using　BCH　as　component　codes　to　obtain　an　Incremental　Redundancy　(IR)　for　source＇s　data.　To　obtain　independent　vertical　parities　from　each　relay　in　the　same　code　space,　different　circular　interleavers　are　proposed　to　interleave　BCH　rows　before　re-encoding　vertically.　A　modified　turbo　product　decoder　to　cope　with　Multiple　Vertical　Parities　(MVP)　is　used　at　the　destination　to　iteratively　decode　the　systematic　data　from　the　source　and　the　vertical　parities　generated　by　the　relays.　Simulation　results　in　Additive　White　Gaussian　Noise　(AWGN)　channel　using　network　scenarios　show　0.3-0.5dB　gain　improvement　in　Bit　Error　Rate　(BER)　performance　over　the　non-cooperative　Turbo　Product　Codes　(TPC).　©2010　IEEE.
