In this work, we present a PNC framework including both uplink and downlink for binary phase shift keying (BPSK). In the uplink, we propose a scheme for detecting network-coded symbol (NCS) with reduced complexity. For the downlink, we propose a transmission scheme of NCS through maximum ratio transmission (MRT) by defining the precoding vector as an average of users' channels. The bit-error-rate (BER) performances and the comparison results with the conventional scheme in both downlink and uplink are provided for the proposed low-complexity PNC framework.eninfo:eu-repo/semantics/openAccessPhysical layer network coding (PNC)Low-complexity schemeConference Object2-s2.0-8516562716810.1109/BalkanCom58402.2023.10167911
