    A New Physical Layer Security Scheme Based on Adaptive Bit Channel Selection for Polar-Coded OFDM by Yuki Kuraya, Hideki Ochiai

    Published 2024-01-01
    “…Specifically, the polar code is constructed by the legitimate receiver based on its observed channel state information (CSI), and the receiver informs the transmitter of the resulting code structure. Since the proposed scheme attempts to improve the block error rate (BLER) performance exclusively for the main channel, it provides a significant performance gain over the wiretap channel, as long as the channel of the eavesdropper is not highly correlated with that of the legitimate receiver. …”
