Analysis of dispersion-enhanced phase noise in CO-OFDM systems with RF-pilot phase compensation.
We show that dispersion-enhanced phase noise (DEPN) induces performance degradations in both conventional CO-OFDM systems and reduced-guard-interval (RGI) CO-OFDM systems employing RF-pilot phase compensation. After analytically studying DEPN, we show that DEPN causes a 2 to 6 dB optical signal-to-noise ratio (OSNR) penalty at transmission distances of 3200 km and 1600 km for 28 and 56 Gbaud QP...
متن کاملInfluence of Pre- and Post-compensation of Chromatic Dispersion on Equalization Enhanced Phase Noise in Coherent Multilevel Systems
In this paper we present a comparative study in order to specify the influence of equalization enhanced phase noise (EEPN) for preand post-compensation of chromatic dispersion in high capacity and high constellation systems. This is – to our knowledge – the first detailed study in this area for pre-compensation systems. Our main results show that the local oscillator phase noise determines the ...

متن کاملPhase Noise Compensation with Limited Reference Symbols
Phase noise (PN) can cause severe link performance degradation in orthogonal frequency division multiplexing (OFDM) systems. In this work, we propose an efficient PN mitigation algorithm where the PN statistics are used to obtain more accurate channel estimates. As opposed to prior PN mitigation schemes that assume perfect channel information and/or require abundant reference symbols, the propo...
متن کاملPhase Noise Influence in Coherent Optical DnPSK Systems with DSP based Dispersion Compensation
We present a comparative study of the influence of dispersion induced phase noise for n-level PSK systems. From the analysis, we conclude that the phase noise influence for classical homodyne/heterodyne PSK systems is entirely determined by the modulation complexity (expressed in terms of constellation diagram) and the analogue demodulation format. On the other hand, the use of digital signal p...
