Abstract
Data communication system for transmitting data codewords of n bytes length over a communication channel (,) from a transmitter (,) comprising a hardware encoder (,) capable of receiving as input an information sequence of n−2t bytes and emitting as output a codeword of n bytes including n−2t information bytes and 2t redundant bytes to a receiver (,) comprising a hardware decoder (,) capable of detecting up to 2t byte-errors and correcting up to t byte errors; the transmitter (,) further comprising a software encoder (,) transforming, in combination with the hardware encoder (,), an information sequence of n−2s bytes with t<s≦2t into a modified sequence, the transmitter (,) emitting encoded codewords including n−2s information bytes and 2s redundant bytes, and the receiver (,) further comprising a software decoder (,) for correcting up to s byte-errors when the hardware decoder (,) has detected errors in the encoded codeword received from the communication channel (20).
