Abstract :
This paper models a 16-QAM coherent optical transmission system and evaluates its performance. The novel guide phase concept and noise averaging concepts are introduced to reduce bit errors. Simulation results show an improvement of the performance of the system with the adaptation of guide phase concept and noise averaging concept.
