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，并突显了对智能技术的需求，这些技术可以扫描可用性并在不中断向授权用户提供服务的情况下机会性地使用无信号信道。加拿大面临着在发展智能带宽管理技术方面保持全球竞争力的挑战，以及管理该行业的政策指导方针，该行业代表着每年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。政府必须面对制定有效政策、引入有效监测和建立保护频谱功能的执行机制的需要。

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.
