Abstract
A communication device includes a generation unit that generates error detection data and an addition unit that adds redundant data including the error detection data to one or a plurality of encoded sequences generated by encoding processing, in which the error detection data is used for error detection of the one or the plurality of encoded sequences. The generation unit generates the error detection data having different lengths according to a predetermined condition.
Claims19
A first communication device, comprising:
- a signal processing unit configured to generate a plurality of encoded sequences based on an encoding processing operation;
- an acquisition unit configured to acquire information of a first criterion, wherein the information indicates a correspondence between a length of at least one of the plurality of encoded sequences and one of a plurality of error detection methods;
- a generation unit configured to:
- select, based on the information of the first criterion and the length of the at least one of the plurality of encoded sequences, an error detection method from the plurality of error detection methods;
- and
- generate error detection data based on the selected error detection method;
- and
- an addition unit configured to add redundant data including the error detection data to the at least one of the plurality of encoded sequences, wherein
- the error detection data is for error detection of the at least one of the plurality of encoded sequences, and
- the generation unit is further configured to generate the error detection data having a plurality of lengths based on a specific condition.
