This paper analyze the channel estimation of rate splitting multiple access (RSMA) wireless network through the full-duplex amplify-and-forward (AF) relay. Basically, the fullduplex transmission can enhance the temporal efficiency, however the loop interference is inevitable issue which occur at the strong user of this proposed network. The orthogonal frequency division multiplexing (OFDM) system is used to provide high data rate communication, assuming the presence of phase noise (PN) at the Local oscillators. Using the least square (LS) estimation, the channel coefficients of the proposed RSMA relay network are estimated. Further, the convex optimization is applied to estimate the phase noise components of this network. The problem is formulated by maximizing the objective function for phase noise optimization subject to transmit power constraints. Bit error rate (BER) of the proposed network is analyzed under binary phase shift keying (BPSK) modulation and 16-quadrature amplitude modulation (QAM). Simulation results demonstrate that the channel estimation of the proposed network achieves the better performance after the PN compensation.Index Terms-amplify and forward (AF) relay, fullduplex transmission, orthogonal frequency division multiplexing (OFDM) and rate splitting multiple access (RSMA).
