Abstract
An error check or correction code coding device is disclosed. In this device, when a main information code is transmitted after an error check or correction code is added thereto, a control code is included in a code group used in calculations upon generation of the error check or correction code, and a bit pattern of the control code is selected to remove a DC component of the bit pattern of the error check or correction code.
