Abstract: An adaptive multi-resolution digital signal processing system (100) implemented on application-specific integrated circuit hardware for compensating optical fiber nonlinearities at terahertz-scale bandwidths in long-haul coherent optical communication networks is disclosed. The system comprises a wideband optical front-end module (110) with frequency comb local oscillators and coherent receiver arrays, a spectral stitching engine (120) achieving sub-picosecond temporal and sub-kilohertz frequency alignment, and a multi-resolution DSP processing core (130) featuring a dynamic spectral partitioning engine (132) that segments the bandwidth into variable-size slices based on estimated impairment profiles. An adaptive nonlinear compensation pipeline (136) with a reinforcement-learning-based step-size controller (138) on a dedicated neural network accelerator dynamically allocates computation steps proportional to impairment severity. Integrated polarization mode dispersion tracking within the back-propagation pipeline and closed-loop performance monitoring enable real-time optimization, achieving measurable signal-to-noise ratio improvement with 30 to 50 percent fewer computation steps.
