Abstract
A decoding device includes a decoding unit that decodes control data to generate decode data, the control data indicating a state of a radio propagation channel; a reliability calculating unit that calculates a reliability indicator indicating a reliability of the decode data; and an outputting unit that outputs decode data whose reliability indicator is larger than a specified threshold; wherein the reliability calculating unit calculates the reliability indicator of decode data to be decoded, based on a similarity indicator indicating a similarity between the decode data to be decoded and previous decode data whose reliability indicator is larger than the threshold.
Claims14
A decoding device comprising:
- a processor, and
- a memory storing instructions that, when executed by the processor, cause the decoding device to
- decode control data to generate decode data, the control data indicating a state of a radio propagation channel;
- calculate a reliability indicator indicating a reliability of the decode data;
- and
- output decode data whose reliability indicator is larger than a specified threshold;
- wherein the reliability indicator is based on a similarity between the decode data and a previous decode data which has been generated by decoding a previous control data indicating a previous state of the radio propagation channel which is measured before the state of the radio propagation channel, and the reliability indicator of the previous decode data is larger than the specified threshold.
A decoding-error detection method comprising:
- decoding control data indicating a radio propagation channel state into decode data;
- calculating a reliability indicator of decode data, based on a similarity between the decode data and previous decode data which has been generated by decoding a previous control data indicating a previous state of the radio propagation channel which is measured before the state of the radio propagation channel, and the reliability indicator of the previous decode data is larger than a threshold, the reliability indicator indicating a decode-data reliability;
- and
- determining that the decoding of the decode data is successful when the reliability indicator of the decode data exceeds the threshold.
