DSP Library for Coherent Optical Systems

DSP Library for Coherent Optical Systems

Brochures

This brochure presents the VPItoolkit DSP Library, developed in collaboration with Fraunhofer HHI and integrated with VPItransmissionMaker Optical Systems and VPIlabExpert. The toolkit provides transmitter and receiver algorithms for channel equalization, synchronization, dispersion compensation, polarization demultiplexing, and nonlinear impairment mitigation. Supporting advanced modulation formats, including probabilistically shaped QAM, it enables simulation and offline processing of experimental signals. Design examples demonstrate shaped 256-QAM transmission and perturbation-based nonlinear equalization, supporting assessment of system performance and DSP complexity trade-offs.
