Abstract
An error correction method and a transmission apparatus used in a transmission using a frame including a header and a payload are provided. In the error correction method and the transmission apparatus, a pseudo error is inserted in check bits of the frame to be transmitted. Thus, an error-correcting function of a transmitter and a receiver can be easily tested. A mismatch of a state of validation or invalidation of the error-correcting function between the transmitter and the receiver can be avoided without affecting a main signal by inserting information on whether or not an error correction is performed in an unused area of the header in the transmitter.
Claims15
An error correction method in a communication using a frame which comprises a header including control data and a payload including actual data, comprising:
- a pseudo error inserting step of inserting a pseudo error in check bits of said frame in a transmitter;
- wherein said check bits are provided in an unused area of an overhead which constitutes a part of said header.
An error correction method in a communication using a frame which comprises a header including control data and a payload including actual data, the method comprising:
- a step of inserting information on a state of validation or invalidation of an error-correcting function of a transmitter in an unused area of said header, said information indicating whether or not an error correction is performed in the transmitter.
A transmission apparatus which performs a communication using a frame which comprises a header including control data and a payload actual data, the apparatus comprising:
- a pseudo error inserting part which inserts a pseudo error in check bits of said frame to be transmitted;
- wherein said check bits are provided in an unused area of an overhead which constitutes a part of said header.
A transmission apparatus which performs a communication using a frame which comprises a header including control data and a payload including actual data, the apparatus comprising:
- an information inserting part which inserts information on a state of validation or invalidation of an error correcting function in an unused area of said header of said frame to be transmitted, said information indicating whether or not an error correction is performed.
