Abstract

The performance of coherent optica] communication systems is significantly degraded by semiconductor laser phase noise. A rate 1/2, constraint length K — 7, convolutional error correcting code with Viterbi decoding is used to improve a 3.5-10 Mbit/s DPSK system. Error correcting coding demonstrates the reduction of the influence of phase noise on BER performance, and significantly lowers the BER floor. Soft decision decoding and hard decision decoding performance is investigated and compared.
