2/3 rate FEC (Forward Error Correcting)

When using this coding scheme, each sequence of 10 bits is followed by 5 parity bits calculated using a (15,10) shortened Hamming code. Any single bit error in the whole 15 bit codeword can be corrected, and any double bit error can be detected.

The packet payload (header, data, and CRC) must be padded out with trailing zeroes to make it a multiple of 10 bits in length.
