Neural Polar Decoders (NPDs) [14] are an advancement in channel coding that combine neural networks (NNs) with polar codes, providing unified decoding for channels with or without memory, without requiring an explicit channel model. They use four neural networks to approximate the functions of polar decoding: the embedding (E) NN, the check ...
Arıkan developed polar codes, a system of coding that provides a mathematical basis for the solution of Shannon's channel capacity problem. [5] He presented a three-session lecture on the polar codes at Simons Institute 's Information Theory Boot Camp at the University of California, Berkeley .
Each transmitted code word in a constant-weight code is designed such that every code word that contains some positive or negative levels also contains enough of the opposite levels, such that the average level over each code word is zero. Examples of constant-weight codes include Manchester code and Interleaved 2 of 5. Use a paired disparity ...
The parity bit may be used within another constituent code. In an example using the DVB-S2 rate 2/3 code the encoded block size is 64800 symbols (N=64800) with 43200 data bits (K=43200) and 21600 parity bits (M=21600). Each constituent code (check node) encodes 16 data bits except for the first parity bit which encodes 8 data bits.
In the broadest sense, a code is a (learnt, or arbitrary, or conventional) correspondence or rule between patterns. It can be an arrangement of physical matter, including the electromagnetic spectrum, that stores the potential (when activated) to convey meaning (or a pre-specified result). [1]

Using low-degree polynomials over a finite field of size , it is possible to extend the definition of Reed–Muller codes to alphabets of size .Let and be positive integers, where should be thought of as larger than .
The NOC is a system to evaluate the effects of nursing care as a part of the nursing process. The NOC contains 330 outcomes, and each with a label, a definition, and a set of indicators and measures to determine achievement of the nursing outcome and are included The terminology is an American Nurses' Association -recognized terminology, is ...
