Ultra-high-speed optical transport based on adaptive ldpc-coded multidimensional spatial-spectral scheme and orthogonal prolate spheroidal wave functions

A system for transmitting data, comprising:

• one or more adaptive Low Density Parity Check (LDPC) encoders configured to encode one or more streams of input data;
• a signal constellation generation module configured to generate one or more signal constellations;
• one or more modulators configured to generate one or more signals using hybrid multidimensional coded modulation;
• an orthogonal prolate spheroid wave function generation module configured to generate orthogonal prolate spheroid wave functions for use as electrical basis functions;
• a spectral band group signal generation module configured to generate one or more spectral band group signals by selecting and combining two or more spectral band groups with center frequencies that are orthogonal to each other;
• and
• one or more spectral-mode-multiplexers and transmitters configured to spectral-mode-multiplex and transmit one or more adaptive LDPC-coded data streams including the one or more spectral band group signals over a transmission medium.
