Technical Terms LDPC code: An error-correcting code with a sparse parity-check matrix that approaches Shannon’s capacity limit with efficient iterative decoding algorithms.

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 ...

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 ...

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 ...
