Hi, Radio Frequency Interface Specification CM-SP-RFIv1.1-C01-050907 p25: "The upstream modulator MUST provide codewords from a minimum size of 18 bytes (16 information bytes [k] plus two parity bytes for T = 1 error correction) to a maximum size of 255 bytes (k-bytes plus parity-bytes). The minimum uncoded word size MUST be one byte." Why the minimun size of the codeword is 18 bytes.Who can tell me,please?
Thanks
