— Reliability-based hybrid ARQ (RB-HARQ) is a recently introduced approach to incremental-redundancy ARQ. The RB-HARQ technique can be used with codes that use soft-input, soft-output (SISO) de-coders, such as convolutional codes and turbo codes. In RB-HARQ, the bits that are to be retransmitted are adaptively selected at the receiver based on the estimated(More)
—We consider the use of selective-retransmission automatic repeat request (ARQ) protocols to improve communication performance on partial-time jamming channels. The schemes that we propose are based on reliability-based hybrid ARQ (RB-HARQ), in which the set of bits to be retransmitted is adap-tively selected based on the estimated a posteriori(More)
