Abstract
A loss correction encoding device having an improved capability of loss correction using LDPC-CC includes a rearranging unit that rearranges information data contained in n information packets according to the constraint length Kmax and the encoding rate (q−1)/q of a check polynomial of the loss correction code used in a loss correction encoding unit. Specifically, the rearranging unit rearranges the information data in such a way that continuous Kmax×(q−1) pieces of information data after rearrangement are contained in different information packets. The rearranging unit distributes the information data to information blocks from n information packets, where n satisfies the formula Kmax×(q−1)≤n.
Claims4
A receiving method for receiving information, comprising:
- receiving a signal comprising information and parity packets generated by performing erasure correction coding on the information with dummy data added;
- generating the dummy data to add the dummy data to the received signal;
- and
- performing erasure correction decoding on the received signal with the dummy data to obtain the information, wherein
- the dummy data is generated to add the dummy data to the information if a length of the information is smaller than a threshold.
A receiving apparatus, comprising:
- a receiver, which, in operation, receives a signal comprising information and parity packets generated by performing erasure correction coding on the information with dummy data added;
- a generator, which, in operation, generates the dummy data to add the dummy data to the received signal;
- and
- an erasure correction decoder, which, in operation, performs erasure correction decoding on the received signal with the dummy data to obtain the information, wherein
- the dummy data is generated to add the dummy data to the information if a length of the information is smaller than a threshold.
