Description
Summary:A novel super forward error correction (super-FEC) coding scheme (viz: the BTC code pattern of BCH(64,57) times BCH(64,57)) based on the block turbo code (BTC) in long-haul optical transmission systems is proposed in this paper. The BTC of Bose-Chaudhur-Hocguenghem (BCH)(64,57)timesBCH(64,57) has been constructed, simulated and analyzed. The simulation results and the performance analyses show that the net coding gain (NCG) of BCH(64,57)timesBCH(64,57) code at the sixth iteration is 0.35 dB more than that of Reed-Solomon (RS)(255,239) + convolutional self orthogonal code (CSOC) (k0/n0=6/7, J=8) code in ITU-T G.975.1 at the third iteration for a BER of 10 -12 and the novel BTC has the advantageous characteristics such as the shorter component code and the rapid encoding/decoding speed, these advantages reduce not only the complexity for implementing the software/hardware but also the time delay for the encoding/decoding. Therefore, the novel BTC coding scheme can be used in large capacity, high-speed and ultra long-haul optical transmission systems. At last, the design and implementation of the novel BTC are also discussed
