Lossless source coding with polar codes
2010 IEEE International Symposium on Information Theory, 2010In 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

We study a family of polar codes whose frozen set is such that it discards the bit channels for which the mutual information falls below a certain (fixed) threshold. We show that if the threshold, which might depend on the code length, is bounded appropriately, a coding theorem can be proved for the underlying polar code.

The International Code for Ships Operating in Polar Waters (Polar Code) has been developed to supplement existing IMO instruments in order to provide a more comprehensive set of provisions to address the increased interests and traffic in the polar regions, and the unique operational, environmental and search and rescue concerns peculiar to these ...

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.

Balanced bipolar codes consist of sequences in which the symbols ‘−1’ and ‘+1’ appear equally often. Several generalizations to larger alphabets have been considered in literature. For example, for the q-ary alphabet {−q + 1, −q + 3, …, q − 1}, known concepts are symbol balancing, i.e., all alphabet symbols appear equally often in each codeword, and ...
