Abstract
A method for transmitting and receiving a source data block using hybrid automatic retransmission request protocol. At the transmitting side, the source data block that is not decoded correctly at the receiving side is divided into a plurality of data segments, each of which may be padded with known data to expand the data segments to be a predetermined lengthen. At the receiving side, when each of the received data packets includes a data segment and a redundancy information segment, decoding is performed based on the received data segment and redundancy information segment extracted from buffered data packets, with chances to restore the data segment that is not decoded correctly in previous decoding processing. The additional decoding chances improve the probability of correctly decoding the erroneous data segment.
