授权认知（cognitions of empowerment）也有译为“授权知觉”。这一概念最早是由Thomas和Velthouse（1990）在Conger等人观点的基础上提出来的。

本文主要考虑择机频谱接入模式下的认知无线电系统，即认知用户只有在授权用户不活动时才可以占用频谱资源。
In this paper, we consider the situation that the user of the cognitive radio system can only user the spectrum resources when them are not occupied by the authorized user.
认知无线电通过对授权频谱进行“二次利用”的方式，为缓解频谱资源缺乏与日益增长的无线接入需求之间的矛盾提供了可行的思路。
Using the licensed spectrum in "secondary utilization" way, cognitive radio provides a feasible solution for contradiction between spectrum resource scarcity and increasing radio access demands.
因此，快速而又准确地检测授权用户信号是认知无线电系统的基础。
Thus, detecting the licensed user's signal quickly and accurately is the foundation of the CR system.
