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 ...
He presented a three-session lecture on the polar codes at Simons Institute's Information Theory Boot Camp at the University of California, Berkeley. [ 6 ] [ 7 ] [ 8 ] The lecture is also featured on the Simons Institute webpage, which includes the slides used by Arıkan in his presentation.

The binary signal is encoded using rectangular pulse-amplitude modulation with polar return-to-zero code. Return-to-zero (RZ or RTZ) describes a line code used in telecommunications signals in which the signal drops (returns) to zero between pulses. This takes place even if a number of consecutive 0s or 1s occur in the signal. The signal is ...
The Biden administration on Tuesday announced new sanctions against Russians accused of producing a bogus video spreading sexual assault allegations against Democratic vice presidential candidate ...
Several bottlenose dolphins in the Gulf of Mexico were found to have traces of fentanyl in their system, shocking scientists and bringing in a new set of questions in the ongoing drug epidemic.
A PDF file is organized using ASCII characters, except for certain elements that may have binary content. The file starts with a header containing a magic number (as a readable string) and the version of the format, for example %PDF-1.7. The format is a subset of a COS ("Carousel" Object Structure) format. [23]
Ukraine needs to get younger people into the military to succeed in the war being waged against it by Russia, U.S. Secretary of State Antony Blinken said on Wednesday. Blinken's comments, in an ...
