Advanced 3R regenerator scheme for high spectral efficient signal waveforms

Abstract

We propose a novel 3R regenerator architecture for highly spectral efficient signals. Through numerical simulations we evaluate its performance and compare with traditional 2R schemes. The results of the analysis demonstrate necessity of 3R for regeneration of NRZ pulses and its relevance for future high capacity transmission systems.

“…only on the phase, regeneration the specific PSA configuration can offer to the signal waveform. The use of more advanced regenerator schemes [20] that enable noise suppression on both signal quadratures are expected to eliminate this effect.…”
