认知无线电技术是无线通信领域与人工智能领域相结合的产物,智能性是其区别于传统无线电的本质属性。先进的人工智能技术在无线电中的成功应用是实现认知无线电的关键。首先介绍了凝聚认知无线电智能思想的认知循环,并对认知无线电的智能实现载体认知引擎,进行了简要描述,说明了人工智能技术在认知无线电实现中的重要作用;然后,从推理、学习和优化的角度对适用于认知无线电的几种人工智能技术进行了总结归纳;最后,介绍了人工智能技术在现有的认知引擎中的应用。
Cognitive radio is a combining creature of wireless communication and artificial intelligence.The essential difference of cognitive radio from traditional radio lies in its intelligence.The key of realization of cognitive radio is the successful application of artificial intelligence to radio.This paper first introduces the cognitive cycle which incorporates intelligence,and then simply describes the cognitive engine which is the core module to realize intelligence.Afterwards,it reviews several artificial intelligence techniques from the view of reasoning,learning and optimization.Finally,it introduces the application of artificial intelligence techniques to cognitive engines existing.
