VPItoolkit DSP Library contains an extensive collection of lab-proven digital signal processing algorithms developed by the Photonic Networks and Systems department at Fraunhofer HHI.
It is available as a pluggable toolkit to VPItransmissionMaker Optical Systems and VPIlabExpert.
The VPItoolkit DSP Library supports a wide range of modulation
formats such as (DP) BPSK, (DP) QPSK, PS QPSK, (DP) mQAM, probabilistically-shaped QAM, 4D set partitioning and provides the following functionalities:
I/Q imbalance correction
