CCSDS Optical Communications High Photon Efficiency Telemetry Signaling Transmit Waveform VHDL/Verilog(LEW-20090-1)

This technology is a VHDL and Verilog implementation of the Consultative Committee for Space Data Systems (CCSDS) Optical Communications High Photon Efficiency Telemetry Signaling waveform. The CCSDS 142.0-B-1 Blue Book from August 2019 is implemented. The implementation includes a data source, transfer frame synchronization marker attachment, slicer, randomizer, cyclic redundancy check, termination bit attachment, convolutional encoder, code interleaver, accumulator, pulse position modulation (PPM) symbol mapper, channel interleaver, codeword sync marker attachment, symbol repeater, slot mapper, and guard slot insertion.
