Abstract
In a puncturing section 102, input memory 201 temporarily stores data inputted to the puncturing section 102, a controller 202 distinguishes data to be added, a switch 203 selects data to be added in accordance with control of the controller 202, an adder 204 adds data (namely, data subjected to repetition by a transmitter side) selected by the switch 203, and output memory 205 temporarily stores data outputted from the puncturing section 102.
Claims7
A decoding apparatus, comprising:
- a receiver that receives a data sequence, in which only a specific portion of the data sequence is subject to repetition at a transmitting side for rate matching;
- a distinguisher that distinguishes the repeated data among the received data sequence;
- an adder that adds the distinguished data and the specific portion of the received data sequence to produce added data that is used to increase a likelihood of correctly decoding the received data sequence;
- a corrector that corrects the added data or all data in the received data sequence to produce corrected data that is within a range that can be decoded;
- and
- a decoder that performs error correction decoding to the corrected data and other data of the received data sequence.
