PURPOSE:To discriminate accurately the insertion position of an additional code by restraining an inserted code by transmit codes before and behind the additional code and an additional code which is inserted (n+1) bits before. CONSTITUTION:A one-bit additional code is inserted into a train of transmit codes at intervals of (n) bits. The inserted additional code is 0 when transmit codes right before and behind the insertion position of the additional code are 1 and 1, or 1 when 0 and 0, and is not constrained by an dditional code which is (n+1) bit before. Then, when the transmit codes right before and behind the insertion position are 1 and 0 or 0 and 1, the additional code 1 which is inserted is 1 if the additional code which is (n+1) bits before or 0 if 1, and code trains at the part are 110 and 011, or 100 and 001. |
