Sequential decoding with ARQ (automatic-repeat-request) and code combining under the
timeout condition is considered. That is, whenever the decoding time of a given packet
exceeds some predetermined duration, decoding is stopped and retransmission of the
packet is requested. However, the unsuccessful packets are not discarded, but are
combined with their retransmitted copies. It is shown that the use of code combining allows
sequential decoding to operate efficiently even when the coding rate R exceeds the …

In this paper we consider sequential decoding with ARQ and code combining under the time-
out condition. That is whenever the decoding time of a given packet exceeds some
predetermined duration, decoding is stopped and retransmission of the packet is requested.
However the unsuccessfull packets are not discarded, but are combined with their
retransmitted copies. We show that the use of code combining allows sequential decoding to
operate efficiently even when the coding rate R exceeds the computational cut-off rate R …
