The Dynamic Phase Transition for Decoding Algorithms
Error correction coding the random structure random graph random arrangement
2015/8/21
The state-of-the-art error correcting codes are based on large random constructions (random graphs, random permutations, . . . ) and are decoded by linear-time iterative algorithms. Because of these f...
