Low complexity digital backpropagation for high baud subcarrier-multiplexing systems.
In this paper, we propose two modifications to reduce the complexity of the subcarrier-multiplexing (SCM) based digital backpropagation (DBP) for high symbol rate SCM systems. The first one is to reduce the number of interfering subcarriers (RS-SCM-DBP) when evaluating the cross-subcarrier nonlinearity (CSN). The second one is to replace the original frequency domain CSN filters with the infini...
متن کاملSubcarrier Multiplexing in Optical Networks
This paper describes the applicability of subcarrier multiplexing to light wave multiple-access networks. It is shown how currently available microwave and light wave components can be used, by using subcarrier multiplexing, to provide high-capacity networks and also how can increase the number of users who support the network.
متن کاملSubcarrier Multiplexing for High-Speed Optical Transmission
The performance of high-speed digital fiber-optic transmission using subcarrier multiplexing (SCM) is investigated both analytically and numerically. In order to reduce the impact of fiber chromatic dispersion and increase bandwidth efficiency, optical single-sideband (OSSB) modulation was used. Because frequency spacing between adjacent subcarriers can be much narrower than in a conventional D...
متن کاملDigital subcarrier multiplexing for fiber nonlinearity mitigation in coherent optical communication systems.
In this work we experimentally investigate the improved intra-channel fiber nonlinearity tolerance of digital subcarrier multiplexed (SCM) signals in a single-channel coherent optical transmission system. The digital signal processing (DSP) for the generation and reception of the SCM signals is described. We show experimentally that the SCM signal with a nearly-optimum number of subcarriers can...
متن کاملDigital subcarrier multiplexing for flexible spectral allocation in optical transport network.
We demonstrate a spectrally efficient digital subcarrier multiplexed (DSCM) coherent optical system for optical transport network. In the proposed system, mutually orthogonal subcarrier channels are digitally generated, which allows a high degree of flexibility in bandwidth allocation and scalability in data rate granularity. The receiver can also dynamically change the number of DSCM channels ...
