MIMO-NOMA oriented CRN Physical Layer Security on Imperfect CSI using Power Optimization and Beamforming Methods

To improve the PLS for a MIMONOMA-based CRN, this paper proposes a transmit-zero-forcing beamforming technique to message alignment, using the ideal channel state data available at the earth station. The above investigation makes use of a large constructability of several cells. Every group has a “primary user” and a “alternate user” who are responsible for implementing the CRN. Both the PU and SU of each cell are assigned locations at random. Finally, when only imperfect CSI is available at the ground station, we propose an eigen wideband technique to enhance the PLS for a CRN based on MIMO-NOMA. Optimal power allocation algorithms are created for both wideband methods to further improve the PLS. Finally, a closed-form expression for the probability of data lost due to Nakagami-m multi-path fading is presented. The following step involves contrasting the results of simulation studies and other methods currently in use with this statement.
