摘　　要：We propose a nonbinary byte-interleaved coded-modulation scheme with inner and outer turbo-like iterative decoder.The net coding gain is 0.6 d B higher than the state-of-the-art binary single parity check(SPC)low-density parity-check(LDPC)based turbo-product counterpart,with adjustable iterations and lower error-floor.We provide the details of Bahl-CockeJelinek-Raviv(BCJR)based inner code decoder and optimum signal constellation design(OSCD)method in this paper.The single-mode fiber(SMF)channel simulation is also discussed.We propose a nonbinary byte-interleaved coded-modulation scheme with inner and outer turbo-like iterative decoder.The net coding gain is 0.6 d B higher than the state-of-the-art binary single parity check(SPC)low-density parity-check(LDPC)based turbo-product counterpart,with adjustable iterations and lower error-floor.We provide the details of Bahl-CockeJelinek-Raviv(BCJR)based inner code decoder and optimum signal constellation design(OSCD)method in this paper.The single-mode fiber(SMF)channel simulation is also discussed.
