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.
Claims6
A transmitting device for transmitting information, comprising:
- a dummy generation circuit configured to generate dummy data to add the dummy data to information;
- a coding circuit configured to perform erasure correction coding on the information with the dummy data to generate information and parity blocks;
- an extracting circuit configured to extract parity data from the information and parity blocks;
- and
- a transmitting circuit configured to transmit the information and the parity data without transmitting the dummy data.
A transmitting method for transmitting information, comprising:
- generating dummy data to add the dummy data to information;
- performing erasure correction coding on the information with the dummy data to generate information and parity blocks;
- extracting parity data from the information and parity blocks;
- and
- transmitting the information and the parity data without transmitting the dummy data.
