Spectrum Resource Optimization for NOMA-Based Cognitive Radio in 5G Communications
In traditional cognitive radio (CR), secondary user (SU) can only access the idle spectrum when primary user (PU) is absent, which has to vacate the spectrum when detecting the presence of the PU. Hence, spectrum utilization of the traditional scheme is very low. Recently, nonorthogonal multiple acc...
