Robust Secure Beamforming Design for Cooperative Cognitive Radio Nonorthogonal Multiple Access Networks
By the integration of cooperative cognitive radio (CR) and nonorthogonal multiple access (NOMA), cooperative CR NOMA networks can improve the spectrum efficiency of wireless networks significantly. Due to the openness and exposure of wireless signals, secure communication is an important issue for c...
