This paper envisages a technique for enhancing the privacy of multi-antenna wireless networks using Artificial Noise (AN). The artificial noise is a form of interference that is designed to degrade the channel quality of eavesdroppers, thereby making it unfeasible for them to capture and decode the transmitted data. The proposed method uses Non-Orthogonal Multiple Access (NOMA). It allows multiple users to share a resource block like a time slot or frequency. This increases the spectral efficiency. The paper evaluates the effectiveness of Artificial Noise (AN) in improving the privacy of the system by measuring the Bit Error Rate (BER) and the eavesdropper's secrecy rate. Simulations show the method significantly enhances the security of the system. The paper also investigates the impact of various system parameters, such as the number of antennas and power allocation coefficients, on the system performance. Overall, the proposed method provides a promising approach to enhancing the security of multi-antenna wireless networks. [ABSTRACT FROM AUTHOR] |
