Hierarchical Polar Coding for Achieving Secrecy Over State-Dependent Wiretap Channels Without Any Instantaneous CSI.
IEEE Transactions on Communications(2016)
摘要
This paper presents a polar coding scheme to achieve secrecy in block fading binary symmetric wiretap channels without the knowledge of instantaneous channel state information (CSI) at the transmitter. For this model, a coding scheme that hierarchically utilizes polar codes is presented. In particular, on the polarization of different binary symmetric channels over different fading blocks, each ch...
