Short-wave communication is a crucial issue in military communication. To improve the performance of short-wave communication, modern communication technology has been utilized. However, a fundamental problem for short-wave is the quality of link restricting the development of short-wave. In this paper, we introduce cognitive radio to the short-wave and proposed a novel algorithm to choose the link based on learning historical information. With the knowledge of historical information, good links can be selected to enhance the reliability of short-wave communication. Finally, simulation results show that our proposed algorithm can considerably improve the short-wave communication performance.
