AdaptBitsForMod()

static void AdaptBitsForMod ( const uint8_t *  bit_seq_in, uint8_t *  bytes_out, size_t  len, size_t  mod_type  )

inlinestatic

Fill-in the bytes of bytes_out with mod_type bits per byte, taken from the bit sequence bit_seq_in.

Parameters

bit_seq_in	The input bit sequence
bytes_out	The output byte array with mod_type bits per byte. It must have space for ceil(len * 8.0 / mod_type) bytes.
len	The number of bytes in bit_seq_in
mod_type	The number of bits in one modulated symbol (e.g., mod_type = 6 for 64-QAM modulation)
