Abstract :
Retransmission protocols are commonly employed for data communications when low bit error rates are required. In this paper, retransmission protocols for frequency-hop communication systems are investigated in which the unit of retransmission is the data contained within a single dwell interval. A scheme is presented for determining the reliability of dwell intervals by counting corrected errors and decoder failures. The performance of this scheme is determined for a channel containing partial-band interference and noise. Comparisons of the dwell retransmission schemes to type-I hybrid ARQ show that dwell retransmission methods give significantly improved performance
