Finite-Length Analysis of Polar Secrecy Codes for Wiretap Channels
Hessam Mahdavifar, Fariba Abbasi
In a classical wiretap channel setting, Alice communicates with Bob through a main communication channel, while her transmission also reaches an eavesdropper Eve through a wiretap…
Hybrid Non-Binary Repeated Polar Codes
Fariba Abbasi, Hessam Mahdavifar, Emanuele Viterbo
Concatenating the state-of-the-art codes at moderate rates with repetition codes has emerged as a practical solution deployed in various standards for ultra-low-power devices such…
Polar Coded Repetition for Low-Capacity Channels
Fariba Abbasi, Hessam Mahdavifar, Emanuele Viterbo
Constructing efficient low-rate error-correcting codes with low-complexity encoding and decoding have become increasingly important for applications involving ultra-low-power devic…
Large Kernel Polar Codes with efficient Window Decoding
Fariba Abbasi, Emanuele Viterbo
In this paper, we modify polar codes constructed with some 2^t x 2^t polarization kernels to reduce the time complexity of the window decoding. This modification is based on the pe…
