Cooperative Spectrum Sensing for Internet of Things Using Modeling of Power-Spectral-Density Estimation Errors

The application of cognitive radio (CR) technology to the Internet of Things (IoT) network can effectively solve the bottleneck problem of spectrum scarcity. As one of the key steps in cognitive radio-based Internet of Things (CR-IoT), the research over spectrum sensing is of great importance. The utilization of the spectrum resource can be described by the power spectral density (PSD), which can ...
