短波通信技术发展至今,其性能和数据传输能力都已提高到一个较高的水平,在军事和民用通信中得到了越来越广泛的应用,但短波通信还存在信道质量可靠性低、质量差的缺点,这依然是制约短波通信发展的重点问题。为此可以将认知无线电技术应用到短波通信系统中,提出了一种基于学习历史信息的短波通信链路选择方法,通过学习历史先验信息选取相应时段性能较好的通信链路,旨在提高短波通信的可靠性。 Since the development of HF communication technology, its performance and data transmission ability have been raised to a higher level. It has been more and more widely used in military and civilian communications. However, the short-wave communication has the disadvantages of low channel quality reliability, poor quality The shortcomings, it is still the key issues restricting the development of shortwave communications. Therefore, the cognitive radio technology can be applied to the shortwave communication system, and a method of short-range communication link selection based on learning history information is proposed to select the communication link with better performance in the corresponding period through learning history prior information. Improve the reliability of shortwave communications.
