Serially Concatenated Polar Codes

open access: yesIEEE Access, 2018
Simulation results show that the performance of polar codes is improved vastly by using polar codes as inner codes in serially concatenated coding schemes.

Concatenated Polar codes [PDF]

open access: yes2010 IEEE International Symposium on Information Theory, 2010
Polar codes have attracted much recent attention as the first codes with low computational complexity that provably achieve optimal rate-regions for a large class of information-theoretic problems. One significant drawback, however, is that for current constructions the probability of error decays sub-exponentially in the block-length (more detailed ...

Polar Codes’ Simplicity, Random Codes’ Durability [PDF]

open access: yesIEEE Transactions on Information Theory, 2021
Over any discrete memoryless channel, we build codes such that: for one, their block error probabilities and code rates scale like random codes'; and for two, their encoding and decoding complexities scale like polar codes'. Quantitatively, for any constants $ , >0$ such that $ +2 <1$, we construct a sequence of error correction codes with ...

Polar-Coded Modulation

open access: yesIEEE Transactions on Communications, 2013
A framework is proposed that allows for a joint description and optimization of both binary polar coding and $2^m$-ary digital pulse-amplitude modulation (PAM) schemes such as multilevel coding (MLC) and bit-interleaved coded modulation (BICM). The conceptual equivalence of polar coding and multilevel coding is pointed out in detail.

Systematic Polar Coding [PDF]

open access: yesIEEE Communications Letters, 2011
Polar codes were originally introduced as a class of non-systematic linear block codes. This paper gives encoding and decoding methods for systematic polar coding that preserve the low-complexity nature of non-systematic polar coding while guaranteeing the same frame error rate.

Compound polar codes

open access: yes2013 Information Theory and Applications Workshop (ITA), 2013
A capacity-achieving scheme based on polar codes is proposed for reliable communication over multi-channels which can be directly applied to bit-interleaved coded modulation schemes. We start by reviewing the ground-breaking work of polar codes and then discuss our proposed scheme.

Polarization coded aperture

open access: yesOptics Express, 2006
Two examples are presented to illustrate the advantages of polarization coded apertures, in which the incoming light will rotate its polarization at a portion of an aperture. In the first example the depth of field of a diffraction limited lens is increased without sacrificing the light throughput; in the second example the axial focal intensity of a ...

Universal polar codes

open access: yes2014 IEEE International Symposium on Information Theory, 2014
Polar codes, invented by Arikan in 2009, are known to achieve the capacity of any binary-input memoryless output-symmetric channel. One of the few drawbacks of the original polar code construction is that it is not universal. This means that the code has to be tailored to the channel if we want to transmit close to capacity. We present two "polar-like"

Polar codes and polar lattices for the Heegard-Berger problem [PDF]

open access: yes, 2017
Explicit coding schemes are proposed to achieve the rate-distortion function of the Heegard-Berger problem using polar codes. Specifically, a nested polar code construction is employed to achieve the rate-distortion function for doublysymmetric binary ...

Polar Code decoder exploration framework [PDF]

open access: yesAdvances in Radio Science, 2018
The increasing demand for fast wireless communications requires sophisticated baseband signal processing. One of the computational intense tasks here is advanced Forward Error Correction (FEC), especially the decoding.
