MULTIPLE COMPONENT CODES BASED GENERALIZED LOW-DENSITY PARITY-CHECK CODES FOR HIGH-SPEED OPTICAL TRANSPORT

摘要

Systems and methods for data transport, including encoding streams of input data using generalized low-density parity check (GLDPC) encoders, the one or more GLDPC encoders being configured to generate GLDPC coded data streams using a plurality of component local codes to improve error correction strength, employ single-parity checks and two or more local block codes during generation of the GLDPC codes, and enable continuous tuning of code rate using the generated GLDPC codes. Signals may be generated using mappers, the mappers configured to assign bits of signals to signal constellations and to associate the bits of the signals with signal constellation points. The signal may be modulated using an I/Q or 4-D modulator composed of one polarization beam splitter, two I/Q modulators, and one polarization beam combiner. The modulated signals are multiplexed using a mode-multiplexer, transmitted over a transmission medium, and the signals are received and decoded using GLDPC decoders.

encoding one or more streams of input data using one or more generalized low-density parity check (GLDPC) encoders, the one or more GLDPC encoders being configured to:
generate GLDPC coded streams using a plurality of component local codes to increase error correction strength;employ single-parity checks and two or more local block codes during generation of the GLDPC coded streams; andenable continuous tuning of code rate using the generated GLDPC coded streams; generating one or more signals using one or more mappers, the mappers configured to assign bits of one or more signals to one or more signal constellations and to associate the bits of the one or more signals with one or more signal constellation points; modulating the signal from mapper using either I/Q or 4-D modulator composed of one polarization beam splitter, two I/Q modulators, and one polarization beam combiner;
