Polar Coding for the General Wiretap Channel (1410.3812v1)
Published 14 Oct 2014 in cs.IT, cs.CR, and math.IT
Abstract: Information-theoretic work for wiretap channels is mostly based on random coding schemes. Designing practical coding schemes to achieve information-theoretic security is an important problem. By applying the two recently developed techniques for polar codes, we propose a polar coding scheme to achieve the secrecy capacity of the general wiretap channel.
