Addendum to “ Feedforward Carrier Recovery for Coherent Optical Communications
In a previous paper [1], we noted when the transmitted signal constellations has rotational symmetry, laser phase noise can be mitigated using non-data-aided (NDA) feedforward (FF) carrier recovery. The structures of a FF carrier recovery unit and a NDA soft-decision phase estimator were shown in Fig. 3 and 4(a), respectively. We have found that in an NDA FF carrier recovery unit, the order of ...
متن کاملSynchronous Demodulation of Coherent 16-QAM with Feedforward Carrier Recovery
Coherent optical transmission allows for improved bandwidth utilization and impairment compensation of existing optical fiber links and is a key for future communication systems with transmission rates of 112 Gb/s and above. In recent years quadrature phase shift keying (QPSK) was the preferred modulation format because of its robustness on long-haul links [1]–[3]. However, for metropolitan are...
متن کاملHardware-Efficient Coherent Digital Receiver Concept With Feedforward Carrier Recovery for -QAM Constellations
This paper presents a novel digital feedforward carrier recovery algorithm for arbitrary -ary quadrature amplitude modulation ( -QAM) constellations in an intradyne coherent optical receiver. The approach does not contain any feedback loop and is therefore highly tolerant against laser phase noise. This is crucial, especially for higher order QAM constellations, which inherently have a smaller ...
متن کاملResidual Versus Suppressed-Carrier Coherent Communications
This article addresses the issue of when to suppress or not to suppress the transmitted carrier in designing a coherent communication system employing a carrier tracking loop for carrier synchronization. Assuming that a phase-locked loop (PLL) is used whenever there exists a residual carrier and a Costas loop is used whenever the carrier is suppressed, the regions of system parameters that deli...
متن کاملMicroresonator combs for coherent optical communications
This thesis covers the study of microresonator-based optical frequency combs for use in coherent optical communication links. Current links typically utilize several free-running lasers to achieve wavelength-division multiplexing (WDM). Having an integrated frequency comb as a source instead could potentially simplify the transmitter while at the same time open up new possibilities on the digit...
