Constellation Expansion for 100G Transmission

In this letter, we focus on coherently detected, non differentially encoded, polarisation division multiplexed 100G communication systems; through incorporating phase noise in the channel model, we assess the net coding gain achievable by various constellations that can be used in lieu of the conven...
