This paper proposes a low computational complexity timing recovery scheme for DSCM systems and demonstrates its potential application in the field.
Digital subcarrier multiplexing (DSCM) has emerged as a promising solution for long-haul coherent optical communication systems because of its high tolerance to chromatic dispersion (CD) and fiber nonlinearity. A low computational complexity timing recovery scheme for DSCM systems is proposed and simulated in this paper. The computational complexity analyzation and simulation results show that the proposed timing recovery scheme could reduce the computational complexity by 43% under 8 subcarriers.
