Checksum-aided forward error correction of data packets

Abstract

A method, device and system for correcting errors in a group of received packets having a redundant packet. The method includes determining an inconsistent bit indicator for a bit position of the packets, determining a bit reliability indicator indicative of a potential bit error location in at least one packet, calculating a number of potential bit error locations for the bit position and identifying a correctable bit location accordingly. A method, device and system for correcting an error in a received packet. The method is adapted to calculate a checksum value of the received packet, verify if the checksum value is indicative of at least one bit error in the received packet, identify a predefined Checksum Pattern Type (CPT) according to the checksum value and determine at least one bit error event (BEE) accordingly. A method, device and system for decoding a plurality of received fountain encoded symbols.
