Lossless source coding with polar codes

2010 IEEE International Symposium on Information Theory, 2010
In this paper lossless compression with polar codes is considered. A polar encoding algorithm is developed and a method to design the code and compute the average compression rate for finite lengths is given. It is shown that the scheme achieves the optimal compression rate asymptotically. Furthermore, the proposed scheme has a very good performance at

On the polar codes for MIMO

2013 International Conference on Wireless Communications and Signal Processing, 2013
Polarization, first introduced by Arikan, is a phenomenon that after some processing of a channel, the resulted channels are either almost clean channels or useless channels. In this paper we propose three schemes to polarize a MIMO channel and design the corresponding polar codes. In the first two schemes, the MIMO channel is decomposed into different

Polar-Code Construction of Golay Codes

IEEE Communications Letters, 2018
This letter proposes a reinterpretation of the classical binary Golay codes as Polar codes with additional inner permutations and puncturing. This establishes a novel relationship between algebraic codes and codes based on Kronecker products, like polar codes.

Sliced polar codes

2016 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2016
A variation on channel polarization coding is presented. In standard channel polarization coding the code length is an integral power of two. Our scheme allows modifying the code at the graph definition level to an arbitrary blocklength. Working at the graph definition level of the code enables the utilization of the newly produced codes for every ...

Cyclic polar codes

2015 IEEE International Symposium on Information Theory (ISIT), 2015
Arikan introduced polar codes in 2009 and proved that they achieve the symmetric capacity, under low-complexity successive cancellation decoding, of any binary-input discrete memoryless channel. Arikan's construction is based on the Kronecker product of 2-by-2 matrices and it was extended to larger matrices by Sasoglu et al. in 2010.

A study on channel polarization and polar coding

2011 9th IEEE International Conference on ASIC, 2011
In 2006, Arikan introduced the method of channel polarization on which one can construct efficient capacity-achieving codes, called polar codes, for any binary discrete memoryless channel (B-DMC). In this letter, we will give a description of the main ideas and mechanisms of this kind of codes.
