Abstract
An error correction decoding method using a correlating decoding technique is provided. The method includes the steps of estimating a decoding reliability of a decoding result using one or more correlation values acquired in a correlating process; and correcting the decoding result according to the decoding reliability.
Claims15
An error correction decoding method using a correlating decoding technique, comprising the steps of:
- estimating a decoding reliability of a decoding result using one or more correlation values acquired in a correlating process;
- and
- correcting the decoding result according to the decoding reliability.
A communication apparatus that uses a correlating decoding technique to decode a portion or all of received signals, comprising:
- a decoding reliability estimator configured to estimate a decoding reliability of a decoding result using one or more correlation values acquired in a correlating process;
- and
- a correcting unit configured to correct the decoding result according to the decoding reliability.
A communication apparatus comprising:
- a receiving unit configured to receive a decoding reliability from a second communication apparatus being in communication with the communication apparatus;
- and
- a control unit configured to dynamically control a transmission parameter for an information item to be decoded such that the decoding reliability satisfies a required quality.
A digital transmission system including a first communication apparatus and a second communication apparatus communicating with each other,
- wherein the first communication apparatus uses a correlating decoding technique to decode a portion or all of signals, and includes
- a reliability estimator configured to estimate a decoding reliability of a decoding result using one or more correlation values acquired in a correlation process;
- a correcting unit configured to correct the decoding result according to the decoding reliability;
- and
- transmitting means configured to transmit the decoding reliability to the second communication apparatus;
- and
- wherein the second communication apparatus includes
- a receiving unit configured to receive the decoding reliability from the first communication apparatus;
- and
- a control unit configured to dynamically control a transmission parameter for information to be decoded such that the decoding reliability satisfies a required quality.
