Viterbi Decoder


The Viterbi decoder finds the most likely sequence of transmitted bits based on the received signal. It uses the
Viterbi algorithm, a dynamic programming algorithm, to perform this task. The algorithm considers all possible
paths through the code to calculate the most likely sequence of bits based on the received signal. It then selects
the path with the highest likelihood.


Features and Benefits


  • Supports soft input widths of 3-bit or 4-bit
  • Supports user-defined traceback lengths. The default value is 20.
  • Supports unipolar and bipolar data types
  • Supports code rate 1/2
  • Supports constraint length 7

Licensing Options


The Viterbi decoder encrypted RTL is freely available with any Libero license.
