This letter proposes a new retransmission control scheme for slow-frequency-hopped communication systems, in which the number of (re)transmitted packets is adaptively decreased in a certain period. Performance of the proposed scheme is analyzed and compared with that of the conventional scheme in terms of the normalized throughput and the 98% packet transmission delay. The numerical results show the superiority of the proposed scheme.
