2 unusual facts about Viterbi algorithm


Space–time trellis code

However, being based on trellis codes, they are more complex than STBCs to encode and decode; they rely on a Viterbi decoder at the receiver where STBCs need only linear processing.

Torleiv Maseng

His work included the standard use of channel estimation and the combination of equalization, error correcting codes and modulation in which the Viterbi algorithm was used by all components.


Semiring

Similarly, the Viterbi algorithm for finding the most probable state sequence corresponding to an observation sequence in a Hidden Markov model can also be formulated as a computation over a (max, ×) algebra on probabilities.
