ViterbiDekoder

The ViterbiDekoder, or Viterbi decoder, is an algorithm used for decoding convolutional codes. Developed by Andrew Viterbi in 1967, it finds the most likely sequence of hidden states that results in a sequence of observed events. This is particularly useful in digital communication systems where data can be corrupted by noise during transmission. The Viterbi algorithm employs a dynamic programming approach to efficiently search through all possible state sequences. It operates by maintaining a set of "survivor paths" at each time step, representing the most probable path leading to each possible state. At each subsequent time step, the algorithm calculates the likelihood of extending each survivor path with the new received symbol and selects the path with the highest probability for each state. This process continues until the end of the received sequence, at which point the path that ends in the final state with the highest overall probability is chosen as the decoded message. The Viterbi algorithm's efficiency and effectiveness have made it a cornerstone of modern error correction coding, widely implemented in applications such as satellite communications, mobile telephony, and digital television broadcasting. Its ability to reconstruct the original data with high accuracy even in the presence of significant noise is crucial for reliable data transmission.
