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.

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

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.

Parsing the Polarity Code

Nature Reviews Molecular Cell Biology, 2004
Cell polarization is used both to mediate physical fates, as, for example, in orientated cell migration, and to specify differential phenotypic fates, as in the asymmetric division of stem cells. Strikingly, the same sets of conserved proteins are used throughout the Metazoa for these purposes.
