This project implements decoding of Low-Density Parity-Check (LDPC) codes using Deep Reinforcement Learning. A DQN agent learns a bit-flipping policy that sequentially corrects errors in noisy ...

Non-binary low-density parity-check (LDPC) codes extend conventional binary LDPC schemes by operating over larger Galois fields, affording stronger error-correction ...

The room we are in is locked. It is windowless and lit from above by a fluorescent bulb. In the hallway outside—two stories beneath the city of London—attendants in dark suits patrol silently, giving ...

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

Researchers at Skoltech have presented new generalized LDPC codes (Generalized Low-Density Parity-Check Codes, GLDPC)—a practical solution that operates faster than modern solutions from the 5G ...

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 ...

Scientists have pinpointed brain activity related to inner speech—the silent monolog in people's heads—and successfully decoded it on command with up to 74% accuracy. "This is the first time we've ...

Researchers have conducted groundbreaking research on memristor-based brain-computer interfaces (BCIs). This research presents an innovative approach for implementing energy-efficient adaptive ...

Abstract: We enhance coarsely quantized LDPC decoding by reusing computed check node messages from previous iterations. Typically, variable and check nodes update and replace old messages every ...

In this paper, both the high-complexity near-ML list decoding and the low-complexity belief propagation decoding are tested for some well-known regular and irregular LDPC codes. The complexity and ...
