Abstract
A code-error correcting device which comprises a circuit for generating a pseudo-random or quasi-random function and which computes the EXCLUSIVE OR of digital information and an output of the circuit for generating the pseudo-random function and further supplies the computed value of the EXCLUSIVE OR to a digital modulator as an input thereof and in which an initial value for generating the pseudo-random function by the circuit for generating the pseudo-random function is set to be the address information or data block information related to the address information. Thereby, the receiving system can stably perform synchronous detection and bit synchronization on the basis of these turning points. Further, the capability of detecting address errors can be improved or increased and omission of the address error can be decreased.
