In this paper, we consider secure communications for a five-node cognitive wireless network system including one primary user (PU) pair and one secondary user (SU) pair in presence of one eavesdropper. The secrecy transmission process departs into two equal time phases. To ensure transmission process safety, the primary source and receiver are allowed to deliver artificial noise to interfere the eavesdropper. To obtain higher spectrum efficiency, we propose an anti-interference spectrum access… CONTINUE READING
