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.
