The future wireless communication system demands enhanced security and reliability than the current systems. In this article, a more simple yet efficient approach is proposed for achieving reliable and secure communication in MISO-NOMA system. This system is capable to provide enhanced confidential communication as well as inter-user interference cancellation without using SIC method. As NOMA was rejected under the name MUST in release 16 of 3GPP we have analyzed its previous limitations and improved its performance. The proposed algorithm combines the benefit of pre-coder matrices with antenna diversity to provide simple, reliable and secure communication without complex processing at the receivers in downlink scenarios. The effectiveness of the proposed algorithm is presented via simulation results.
