VPItoolkit™ DSP Library
contains an extensive collection of lab-proven digital signal processing algorithms. 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) 16QAM, 4D set partitioning.
VPItoolkit™ QKD
is an add-on to VPItransmissionMaker Optical Systems providing module libraries for system-level simulations of discrete variable (DV) and continuous variable (CV) quantum key distribution (QKD) scenarios. It contains modules for QKD transmitters and receivers, parameter estimation, and secret key rate calculation.
