Adaptive Spectrum Allocation and Sensing for Cognitive Communication

对宽带频谱不断增长的需求导致了对频谱利用率的重新评估，并强调了对智能技术的需求，这些技术可以扫描可用性并适时使用无信号信道，而不会中断对授权用户的服务。加拿大面临的挑战是，在智能带宽管理技术的发展方面保持全球竞争力，以及管理这一行业的政策指导方针，这一行业每年代表着数十亿美元的潜在市场。目前，国际上正在推动生产和部署智能技术以提高频谱利用率。各国政府必须正视建立有效政策、引入有效监测和建立执行机制以保障频谱功能的需要。

The ever-increasing demand for broadband spectrum has led to a re-evaluation of spectrum utilization, and highlighted the need for smart technologies that can scan availability and opportunistically use signal free channels without interrupting services to licensed users. Canada faces the challenge of remaining globally competitive in the development of smart bandwidth management technologies as well as the policy guidelines to manage this industry which represents a potential market in the billions annually. At present, there is an international push to produce and deploy intelligent technology to improve the utilization of spectrum. Governments must confront the need to establish efficient policies, introduce effective monitoring, and institute enforcing mechanisms to safeguard the functionality of the spectrum.
