Abstract: This paper proposes a novel Viterbi-Like successive cancellation (VL-SC) decoding algorithm for polar codes. The algorithm employs the bit log-likelihood-ratio as the “penalty value” within ...

After poring over recordings from sperm whales in the Caribbean, UC Berkeley linguist GasperBegus had an unlikely breakthrough. According to a new study from Begus and his colleagues with Project CETI ...

ABSTRACT: A new nano-based architectural design of multiple-stream convolutional homeomorphic error-control coding will be conducted, and a corresponding hierarchical implementation of important class ...

Most experimental brain-computer interfaces (BCIs) that have been used for synthesizing human speech have been implanted in the areas of the brain that translate the intention to speak into the muscle ...

Abstract: We apply the innovations method to Viterbi decoding of convolutional codes. First, we calculate the covariance matrix of the innovation (i.e., the soft-decision input to the main decoder in ...

With AV1 hardware decode on mo­bile devices stuck in the mid-to-low teens as of 2025, and with VVC at zero, it’s clear that the race to supplant H.264 and HEVC will be contested with software-only ...

The historian Daniel Immerwahr says that Trump’s embrace of imperialist adventuring is not just about business interests—it’s an appeal to masculinity which “seems to sell.” The Political Scene ...

A lab develops brain wave decoder that may help in spinal cord injury rehabilitation. When a person sustains an injury to the spinal cord, the normal communication between the brain and the spinal ...

Add a description, image, and links to the viterbi-decoder topic page so that developers can more easily learn about it.

(A) Physical drawing of the experimental platform. (B) Schematic diagram of the experimental platform connection. (C) Enlarged view of the skull fixation device. (D) Schematic diagram of the 10–20 ...
