Abstract(in English) | Reliability Based Hybrid ARQ (RB-HARQ) is an ARQ scheme using the modified feedback. In the RB-HARQ, the receiver returns both NAK signal and unreliable bit indices if the received sequence is not acknowledged. Since the unreliable bit index is determined by the bitwise posterior probability, better approximation of that probability is crucial. Assuming the systematic codes, the proposed RB-HARQ scheme has two features for this approximation: (1) The sender retransmits newly encoded parity bits corresponding to the unreliable information bits; (2) The retransmitted parity bits as well as the initial received sequence are put all together to perform the message passing decoding. |
