Summary:PROBLEM TO BE SOLVED: To add the sync data for detecting the head of a packet correctly. SOLUTION: In drawing 7 (A), a PR4 decode part receiving the input of data to which a sync pattern H1'01011111111110000' or a sync pattern H1''million' is added, calculates the exclusive OR of input data and the data delayed 2 bits and a sync detecting part detects the head of the packet by detecting a bit string '001000000001100'. In drawing 7 (B), the PR4 decode part receiving the input of the data to which a sync pattern H2'10011111111110000' or a sync pattern H2''01100000000001111' is added, calculates the inputted data and the exclusive OR delayed the 2 bits and the sync detecting part detects the head of the packet by detecting the receiving sync pattern in drawing 7 (A) and the bit string '111000000001100' different the 2 bits.
