Abstract

Abstract:

This paper studied a multiple-input single-output downlink communication system based on the Rate Splitting Multiple Access (RSMA) technique. RSMA provids optimal performance by decoding the information of the intended user and treating the information of the remaining users as noise. In addition, the public information in RSMA is not only useful data for the user, but could also be used to interfere with external eavesdroppers. For practical application scenarios where users were far away from the base station, this paper proposed an RSMA-based relay cooperative transmission scheme in the presence of eavesdroppers. The transmission process was divided into two time slots: in the first time slot, the relay receives, decodes and forwards the signal; in the second time slot, the user received the signal from the relay. Each user first decoded the public message and then decoded its private message by applying successive interference cancellation (SIC). Based on this, closed expressions for the outage probability and eavesdropper intercept probability of the system under Rayleigh fading channels were derived. Finally, the correctness of the theoretical analysis was verified by Monte Carlo simulation. The simulation results show that a reasonable choice of the transmit power and the distance between nodes can effectively reduce the interruption probability of the system as well as better trade-off between the security and reliability of the system.
