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 ...

The codes all work by transforming a horde of error-prone qubits into a much smaller band of “protected” qubits that rarely make mistakes. But in the two simulations, low-density parity check — or ...

The IPrium-LDPC-CCSDS-AR4JA-Encoder-Decoder IP Core implements Low Density Parity Check (LDPC) forward error correction algorithm for AR4JA CCSDS 131 ...

A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...

Low-density parity-check (LDPC) codes represent one of the most effective error-correcting schemes available, approaching Shannon’s theoretical limit whilst maintaining a relatively low decoding ...

January 6, 2025 - Global IP Core Sales - In the Sum Product Algorithm (SPA) for LDPC decoding the messages are sent from the check nodes to bit nodes after the SPA steps which are (for one iteration): ...
