WebThis is an extensive survey on the architecture and protocol design issues for cognitive radio networks or dynamic spectrum access (DSA) networks, also referred to as NeXt Generation (xG) networks. Q. Zhao and B. M. Sadler, “A survey of dynamic spectrum access,” IEEE Signal Processing Magazine, vol. 24, no. 3, pp. 79-89, May 2007. WebThe concept of Cognitive Radio (CR) has been considered as a promising technology to solve the problem of spectrum scarcity through the utilisation of various unutilised spectrum bands. In a future network deployment, multiple radio access networks may coexist having different characteristics.
WebApr 19, 2024 · Dynamic spectrum access (DSA) is a promising paradigm to remedy the problem of inefficient spectrum utilization brought upon by the historical command-and-control approach to spectrum allocation. In this article, we investigate the distributed DSA problem for multiusers in a typical multichannel cognitive radio network. WebField measurements can confirm signal levels of known transmitters and, more importantly, help identify undocumented RF sources which would otherwise be impossible to detect. • …
