Design of Asynchronous Cooperative Spectrum Sensing Scheme and Wideband Dynamic Spectrum Access Algorithm for Cognitive Radio NetworksDownload
Dynamic spectrum access (DSA) is a promising solution for mitigating the problem of crowded radio spectrum and enhancing the utilization efficiency of spectrum resources, making it a hot research topic. In DSA, spectrum sensing is crucial and cooperative spectrum sensing (CSS) is confirmed as a...
Cognitive radio has been considered as a promising way to deal with the overcrowded wireless spectrum. In cognitive radio, when licensed users (primary users) do not use their licensed spectrum, they may lease the spectrum to unlicensed users (secondary user). In a cognitive radio network, a...
Future fifth generation (5G) cellular standards incorporate new emerging technologies such as cognitive radio, device to device (D2D), interweave, energy harvesting, massive MIMO, and millimeter wave networks. However, the achievable gains of these technologies are limited by the spatial...
