Method and device for error correction in the static header information of a received packet

摘要

When a received packet contains static information and a CRC section (104) detects an error, the static information alone will be read from a buffer (106) and replace the static information of the received packet. A header reproduction section (107) once again reproduces a header, and upon this reproduced header the CRC section (104) performs CRC. If a bit error is detected, the received packet will be discarded. If no error is detected, determining that the bit error was in the static information portion in the header of the received packet, the packet in which the static information has been replaced will be output as a received packet.
