论文摘要
{\ it认知无线电}网络的信息理论限制已在探索中已有十多年了。尽管许多网络的限制是未知的,包括带有两对发射器接收器的最简单情况,在几种情况下,可以准确或最多达到恒定间隙。本章的目的是提供有关使用认知无线电技术时与最佳通信相关的传输技术性质的见解。 %,重点是5G网络。在对不同认知系统的信息理论分析中概述了艺术的状态,我们强调了基于这项技术的无线网络设计范式中应考虑的能力调查或能力实现策略的显着特征/点。特别是,我们强调认知无线电与5G网络的新兴技术的相互作用。
Information-theoretic limits of {\it cognitive radio} networks have been under exploration for more than a decade. Although such limits are unknown for many networks, including the simplest case with two pairs of transmitter-receiver, there are several cases for which the capacity limits are obtained either exactly or up to a constant gap. The goal of this chapter is to provide insights into the nature of transmission techniques associated with optimal communication when cognitive radio technology is used. %, with an emphasis on 5G networks. Outlining the state of the art in the information-theoretic analysis of different cognitive systems, we highlight the salient features/points of the capacity-achieving or capacity-approaching strategies that should be considered in wireless network design paradigms based on this technology. In particular, we emphasize the interaction of cognitive radio with emerging technologies for 5G networks.
