EVM Based Primary User Monitoring in Cognitive Radio Systems


The periodic sensing requirements in cognitive radios cause interruptions for secondary user (SU) communication. As a result, the throughput of the secondary system during sensing can be very low. In this paper, we propose a monitoring scheme for Orthogonal Frequency Division Multiplexing (OFDM) based cognitive radio which can monitor the spectrum during… (More)
