AbstractMost of studies in cognitive radio have considered that the transmission of secondary users is not allowed within the sensed band during the sensing period. This consideration leads the CR to under utilize the available spectrum while sensing the radio frequency environment. This paper brings the performance of the continuous sensing technique on CR networks, aiming at a higher network throughput than in the classic approach under the same constraints of interference level on the primary user of the spectrum.
