Bibliographical note

Funding Information:
Current research is fully in line with simple analytical theory, and, due to practical constraints associated with compensator bandwidth, symmetry, and transceiver noise, activities are focused on practical issues of complexity and adaptability. However, significant scope for performance improvement is apparent, and will be driven by increasing symbol rates allowing a larger fraction of the nonlinearity to be captured by independent receivers with no phase coherence between channels, development of high SNR transceivers, the introduction of phase-coherence between channels using frequency combs, and for optical implementations, improved symmetrical link design. This paper was funded in part by the EPSRC, grant numbers EP/S003436/1, EP/S016171/1, EP/W002868/1and EP/R035342/1.
