Communication device, communication method, and communication program

摘要

A device receives reception packets including information packets that contains information symbols and check packets that contains check symbols and divides each packet into a plurality of symbols, that configure FEC codes, detects whether each packet of the reception packets is a normal reception packet or an abnormal reception packet, generates a plurality of FEC decode candidates configured by a normal symbol included in the normal reception packet and an uncertain symbol included in the abnormal reception packet and generated to have the uncertain symbol different from one another for each of the FEC codes and performs a first error correction on the plurality of FEC decode candidates, and corrects the FEC codes based on consistent results of the first error correction among a plurality of results of the first error correction that is performed on the plurality of FEC decode candidates.

主权项

1. A communication device for performing a communication with a different communication device, the communication device comprising:
a receiver that receives reception packets including information packets that contains information symbols and check packets that contains check symbols and divides each packet into a plurality of symbols, wherein the information packets and the check packets configure FEC (Forward Error Correction) codes; a first error detector that detects whether each packet of the reception packets is a normal reception packet or an abnormal reception packet; a first error correcting unit that generates a plurality of FEC decode candidates for each of the FEC codes and performs a first error correction on the plurality of FEC decode candidates, wherein each of the plurality of FEC decode candidates is configured by a normal symbol included in the normal reception packet and an uncertain symbol included in the abnormal reception packet and generated to have the uncertain symbol different from one another; and a second error correcting unit that corrects the FEC codes based on consistent results of the first error correction among a plurality of results of the first error correction that is performed on the plurality of FEC decode candidates by the first, error correcting unit.
