The Viterbi algorithm is a dynamic programming algorithm for obtaining the maximum a posteriori probability estimate of the most likely sequence of hidden states—called the Viterbi path—that results in a sequence of observed events.

Andrew James Viterbi (born Andrea Giacomo Viterbi, March 9, 1935) is an electrical engineer and businessman who co-founded Qualcomm Inc. and invented the Viterbi algorithm.

2024年6月6日 · The Viterbi algorithm is a dynamic programming algorithm for finding the most likely sequence of hidden states in a Hidden Markov Model (HMM). It is widely used in various applications such as speech recognition, bioinformatics, and natural language processing.

A Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using a convolutional code or trellis code. There are other algorithms for decoding a convolutionally encoded stream (for example, the Fano algorithm ).

We seek the path through the trellis that has the maximum Pr ( I ∩ O ) At each column (time step) in the trellis, the Viterbi algorithm eliminates all but N possible state sequences. At each time step, the N retained sequences all end in different states.

2024年10月28日 · Andrew Viterbi earned one of the first doctorates in electrical engineering ever granted at USC. The "Viterbi Algorithm", a mathematical formula to eliminate signal interference, paved the way for the widespread use of cellular technology, and catapulted Viterbi into the limelight of wireless communications worldwide.

The Viterbi algorithm (VA) is a recursive optimal solution to the problem of estimating the state sequence of a discrete-time finite-state Markov process observed in memoryless noise. Many problems in areas such as digital communications can be cast in this form.
