Viterbi Decoder Functions

This section describes the functions that perform operations of Viterbi decoding in the V34 receiver. The encoding is performed in accordance with the algorithm that is described in the section 9.6.3 of the ITU-T Recommendation V.34 (see [ITUV34]).

• GetVarPointDV
  Fills the array with the information about points that are closest to the received point.
• CalcStatesDV
  Calculates the states of the Viterbi decoder.
• BuildSymblTableDV4D
  Fills the array with the information about possible 4D symbols.
• UpdatePathMetricsDV
  Searches for the state with the minimum path metric.
