摘要

In this paper, we investigate the energy efficient physical layer security in large scale multiple-input multiple output (MIMO) cognitive radio networks where each secondary user has its imposed quality of service (QoS) constraint in terms of signal-to-interference-plus-noise ratio (SINR). In the proposed system model, eavesdroppers overhear the legitimate communication passively that results in loss in secrecy capacity/rate and jammers jam the legitimate communication with an aim to deteriorate the SINR at the receiver for the users. The legitimate secondary users in cognitive radio networks adapt their transmit waveforms and transmit powers on the fly to find the least jammed/interfered channels to communicate with high achievable data rates. The performance of the proposed approach is evaluated using numerical results obtained from simulations.
