Title
Low-complexity BCH codes with optimized interleavers for DQPSK systems with laser phase noise.
Abstract
The presence of high phase noise in addition to additive white Gaussian noise in coherent optical systems affects the performance of forward error correction (FEC) schemes. In this paper, we propose a simple scheme for such systems, using block interleavers and binary Bose---Chaudhuri---Hocquenghem (BCH) codes. The block interleavers are specifically optimized for differential quadrature phase shift keying modulation. We propose a method for selecting BCH codes that, together with the interleavers, achieve a target post-FEC bit error rate (BER). This combination of interleavers and BCH codes has very low implementation complexity. In addition, our approach is straightforward, requiring only short pre-FEC simulations to parameterize a model, based on which we select codes analytically. We aim to correct a pre-FEC BER of around $$10^{-3}$$10-3. We evaluate the accuracy of our approach using numerical simulations. For a target post-FEC BER of $$10^{-6}$$10-6, codes selected using our method result in BERs around 3$$\\times $$× target and achieve the target with around 0.2 dB extra signal-to-noise ratio.
