Abstract
A Viterbi decoder module includes a branch metric module configured to calculate branch metrics corresponding to a continuous phase modulated signal. Each of the branch metrics corresponds to a respective path between stages of the Viterbi decoder module. A path metric module is configured to calculate a first cost metric associated with the first state of the next stage based on the first branch metric and the second branch metric, and calculate a second cost metric associated with the second state of the next stage based on the third branch metric and the fourth branch metric. A traceback module is configured to determine a maximum likelihood path between stages of the Viterbi decoder based on the first cost metric and the second cost metric. The Viterbi decoder module is configured to output decoded data based on the maximum likelihood path.
