短波电台认知引擎设计

Design of HF Cognitive Engine

短波3G通信技术在通信建链过程的频率选择能力上比2G有了很大提高，但所选频率集只能人工预置，不能在通信过程中选择合适的频率集。认知无线电（Cognitive Radio，CR）技术利用人工智能技术，能根据频谱状态和通信状态实时地选择频率、配置波形参数，达到更好的通信效果。本文介绍了认知无线电技术和认知引擎技术（Cognitive Engine，CE），设计了一种符合当前短波通信设备需求和将来短波通信设备发展方向的认知引擎。

The frequency select capability of HF 3 G communication technology has improved greatly compared with 2G communication technology during the process of communication link es- tablishment. But the selected frequency set can only be preset manually, it can not select the suitable one during the communication process. The cognitive radio technology can chose the frequency and configure wave parameters in real time according to the spectrum and communication state so as to gain the better communication effect. This paper intro- duces the cognitive radio technology and the cognitive engine technology, and designs a cognitive engine which can meet the requirement of current HF communication equipment and fit for the future developing trend of HF communication equipment.
