Reliability-based retransmission criteria for hybrid ARQ
Justus Fricke, Peter Adam Hoeher · IEEE Transactions on Communications · 2009
Bit error probability (BEP) and word error probability (WEP) are used as reliability-based retransmission criteria in conjunction with hybrid ARQ (HARQ) protocols. Instead of exploiting an error-detecting code, the decision for a retransmission is based on the error probability of the decoded word, which can be calculated in or after the decoding process.
