The rigid structure of the current spectrum allocation policies creates a bottleneck for rapidly growing wireless users. On the other hand, the Federal Communication Commission (FCC) measurements reveal that most of the licensed frequency bands are either unused or utilized less than 10% of the time. In order to address the limitations on spectrum usage, the FCC has motivated the use of opportunistic spectrum sharing to make licensed frequency bands accessible for unlicensed wireless users. The intention behind this is to create cognitive capability of wireless devices for concurrent spectrum usage. In cognitive networks, users/radios dynamically adapt to their environment through learning or artificial intelligence with the aim of improving the overall network performance.

当前频谱分配政策的僵化结构为快速增长的无线用户造成了瓶颈。另一方面，美国联邦通信委员会 (FCC) 的测量显示，大多数许可频段要么未使用，要么使用时间不足 10%。为了解决频谱使用的限制，FCC 鼓励使用机会性频谱共享，以使未经许可的无线用户可以使用许可的频段。其背后的目的是创建无线设备的认知能力以实现并发频谱使用。在认知网络中，用户/无线电通过学习或人工智能动态适应其环境，目的是提高整体网络性能。
