TUT6: Universal Decoding by Guessing Random Additive Noise Decoding


Forward error correction decoding has traditionally been a code-specific endeavor. An innovative recent alternative is noise-centric guessing random additive noise decoding (GRAND). Our approach uses modern developments in the analysis of guesswork to create a universal algorithm where the effect of noise is guessed according to statistical knowledge of the noise behavior or through phenomenological observation. The noise effect is removed from the received signal, and the codebook is used simply as a hash check to verify whether the result is in the codebook. The guessing continues until the hash check is correct or the algorithm declares an erasure. This approach provably provides a Maximum Likelihood (ML) decoding for any block code as long as the guesswork order matches the channel statistics. The ability to incorporate statistical knowledge, such as burstiness of noise effects, such as interference or correlated fading channels, or likelihood ratios that come from soft information, can effectively guide the querying of possible noise effects. The algorithms are parallelizable and well suited to hardware implementation. Because of the universal nature of GRAND, it allows use of a variety of different codes, including techniques designed for cryptographic purposes rather than for error-correcting ones. The exploration of the use of different codes, including heretofore undecodable ones, is an interesting facet of GRAND.
