Abstract

In this article, we compute the Secrecy Outage Probability (SOP) and the Probability of Strictly Positive Secrecy Capacity (SPSC) for Cognitive Radio Networks with Adaptive Transmit Power and energy harvesting using multiple antennas. The secondary source harvests power using multiple antennas using node A signal. Node A is a node transmitting Radio Frequency signals. Then, it adapts its power to generate interference at primary receiver $$P_R$$ P R less than T. Our analysis takes into consideration the interference between primary and secondary nodes. In fact, the Signal to Interference plus Noise Ratio is analyzed at the secondary destination in the presence of interference from the primary transmitter. We derive the SOP and SPSC when the secondary source and destination have multiple antennas. The transmission is made from the best antenna of the secondary source to the best receiving antenna at the secondary destination.
