descrambler()

void satnogs::comms::dsp::ccsds::descrambler ( uint8_t * data, size_t len )

static

Descrambles the data in place, based on the CCSDS Randomization procedure Initial seed as specified by CCSDS 231.0-B-3 is all ones

Parameters

data	data to de-randomize. The result is available in place
len	the number of bytes to de-randomize

Note

: While this is an additive synchronous scrambler, scrambling and descrambling is the exact same procedure. This function is only for readability purposes.
