Abstract
In the presence of an eavesdropper, the Rate Splitting (RS) technique has been proposed in a Multiple Access Network in this research. By using RS, a message sent from Base Station (BS) is divided into common and private sections. While the private portion can only be deciphered by the intended recipient, the common portion can be decrypted by anybody. The authors want to create a mathematical model that includes a closed-form analytical expression for secrecy rate in order to shield sensitive data from prying eyes. Following that, RS technology was used in conjunction with Constructive Interference (CI) and Zero Forcing (ZF) precoding techniques. According to the results, CI with RS performs better than ZF with RS.
