Improving SOVA Output Using Extrinsic Informations for Bit Patterned Media Recording Consumer ... WebSoft Output Viterbi Algorithm (SOVA) [4], to calculate an approximate likelihood ratio, which is the soft output for the DQPSK demodulated bits. The method given in [5] uses SOVA for … The soft output Viterbi algorithm (SOVA) is a variant of the classical Viterbi algorithm. SOVA differs from the classical Viterbi algorithm in that it uses a modified path metric which takes into account the a priori probabilities of the input symbols, and produces a soft output indicating the reliability of the … See more 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 … See more The Viterbi algorithm is named after Andrew Viterbi, who proposed it in 1967 as a decoding algorithm for convolutional codes over noisy digital communication links. It has, … See more This algorithm generates a path $${\displaystyle X=(x_{1},x_{2},\ldots ,x_{T})}$$, which is a sequence of states Two 2-dimensional … See more • Expectation–maximization algorithm • Baum–Welch algorithm • Forward-backward algorithm • Forward algorithm • Error-correcting code See more A generalization of the Viterbi algorithm, termed the max-sum algorithm (or max-product algorithm) can be used to find the most likely assignment of all or some subset of latent variables in a large number of graphical models, e.g. Bayesian networks See more Consider a village where all villagers are either healthy or have a fever, and only the village doctor can determine whether each has a fever.
