Researchers at Skoltech have presented new generalized LDPC codes (Generalized Low-Density Parity-Check Codes, GLDPC)—a ...

Dynamic scheduling and decoding algorithms have become pivotal in advancing the performance of error-correcting codes. Recent innovations have focused on refining Low-Density Parity-Check (LDPC ...

The LDPC decoding algorithm gains more than 2.5 dB against Reed-Solomon-based solutions of the same code rate. This gain allows for more reliable data transmission, less power consumption or for an ...

Computation of the Sum-Product algorithm for 32 iterations using high precision 64 bit arithmetic would be prohibitively expensive, our stochastic decoder implementation provides less than 0.2 dB loss ...

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 ...
