Advanced Digital Signal Processing and Variable-Rate Coding for Unrepeatered Optical Transmission

چکیده
In this paper, we evaluate the selective combination of algorithms for fiber nonlinearity compensation, transceiver impairments mitigation and variable-rate coding in unrepeatered optical transmission. A post-emphasis filter a two-stage 4×4 multiple-input multiple-output equalizer compensate impact bandwidth limitations in-phase quadrature skew. Nonlinear compensation is accomplished by fast-converging adaptive digital back-propagation algorithm maximum likelihood sequence estimation. Forward error correction provided spatially-coupled low-density parity-check code. The performance complexity proposed subsystems are experimentally evaluated wavelength division multiplexing transmission 17×200-Gb/s (DP-16QAM 32-GBd) channels over 350-km large effective area low-loss single-mode fibers. experimental results different combinations elucidate trade-off

متن کاملDigital Signal Processing and Lsi in Modems for Data Transmission*)
Digital signal processing and LSI are steadily being introduced in the field of data transmission. Still there is a noticeable discrepancy between existing design possibilities and actual practical application. The backgrounds of this contrast are briefly considered in this paper. A short survey on data modems is presented showing the wide diversification that has to be coped with. The main par...
