A Survey of Dynamic Spectrum Access: Signal Processing and Networking Perspectives
Qing Zhao, Ananthram Swami · 2007
In this paper, we provide a survey of dynamic spectrum access techniques. Various approaches envisioned for dynamic spectrum access are broadly categorized under three models: dynamic exclusive use model, open sharing model, and hierarchical access model. Based on this taxonomy, we provide an overview of the technical challenges and recent advances under each model.
