Polar codes for channel and source coding

open access: yes, 2009
The two central topics of information theory are the compression and the transmission of data. Shannon, in his seminal work, formalized both these problems and determined their fundamental limits. Since then the main goal of coding theory has been to find practical schemes that approach these limits.

Short-Block Polar-Coded Reverse and Direct Reconciliation in CV-QKD

open access: yesIEEE Open Journal of Vehicular Technology
Continuous-variable quantum key distribution (CV-QKD) is a promising technique of supporting quantum-safe wireless networks in the emerging 6 G era, mapping quantum information onto the amplitude or phase of electromagnetic waves.

Polar codes for the m-user multiple access channels [PDF]

open access: yes
Polar codes are constructed for m-user multiple access channels (MAC) whose input alphabet size is a prime number. The block error probability under successive cancelation decoding decays exponentially with the square root of the block length.
