The CCSDS 231.0-B-3 LDPC codes with rates of 1/2 and uncoded block lengths of 64 and 256 bits are specially designed for telecommand (TC) and free space optical applications. Encoder and decoder IP ...

April 21, 2022-- Xylon has just revealed two new IP products for lossless and on-the-fly MJPEG video compression and decompression. New logiJPGE-LS and logiJPGD-LS IP cores from the logicBRICKS by ...

The three-dimensional world of ordinary experience—the universe filled with galaxies, stars, planets, houses, boulders, and ...

Abstract: Low density parity check (LDPC) lattices were the first family of lattices equipped with iterative decoding algorithms. We introduce quasi-cyclic LDPC (QC LDPC) lattices as a special case of ...

We have all been there. An invitation arrives in your mailbox, you open and instantly read the dress code: It's black tie. But what does black tie mean in an age when everything seems to be casual ...

While superposition codes asymptotically reach the Shannon capacity, we show that our iterative decoder is limited by a phase transition similar to the one that happens in low density parity check ...

This paper describes the development of an algorithm for verification of signatures written on a touch-sensitive pad. The signature verification algorithm is based on an artificial neural network. The ...
