Optimal Spectrum Sensor Assignment in Multi-channel Multi-user Cognitive Radio Networks
Journal of Telecommunications and Information Technology, 2018 Accurate detection of spectrum holes is the most important and critical task in any cognitive radio (CR) communication system. When a single spectrum sensor is assigned to detect a specific primary channel, then the detection may be unreliable because of
