ERROR CORRECTION SYSTEM AND TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To easily confirm a function of error correction for a transmitter side and a receiver side for each bit without giving effect on a main signal in the error correction system in communication using a frame consisting of a header and a payload. SOLUTION: A transmitter side FEC arithmetic section 10 generates an error correction cheek bit to STS-N data. A pseudo error generating section 11 adds a pseudo error to a bit at an optional position of a check bit inserted to an overhead not in use and calculated by the transmitter side FEC arithmetic section 10 on the basis of a pseudo error addition setting signal and transmits the result to an MUX section 12. The MUX section 12 multiplexes the STS-N data and the check bit and transmits the error correction code.
