Abstract:
A method for correcting information bits (IB) of a data packet (P), which have been subjected to errors due to a transmission of said data packet (P) between a transmitter (TM) and a receiver (RC), whereina) the original information bits (IB) of said data packet (P) before transmission are reordered at said transmitter (TM) using a selected reordering pattern (REORD-A, REORD-B, REORD-C) in response to a parity bit request issued by said receiver (RC);b) a set of parity bits (PB, PC) for said reordered original information bits are derived and transmitted by said transmitter (TM) to said receiver (RC);c) said erroneous information bits received at said receiver (RC) are reordered using said selected reordering pattern (REORD-A, REORD-B, REORD-C); andd) said reordered erroneous information bits (IB) are corrected at said receiver (RC) using said set of parity bits (PB, PC) received from said transmitter (TM).
