一种新的短波信道选择方法

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。

A Novel Channel Selection Approach in HF Communication

Short-wave communication is a crucial issue in military communication.To improve the performance of short-wave communication,the modern communication technology is widely employed.However,a fundamental problem of short-wave communication is low reliability and quality of its communication channel.In this paper,the introduction of cognitive radio to the short-wave communication is suggested,and a novel link-selection algorithm based on learning historical information is proposed.With the knowledge of histori...
