Abstract :
This work addresses the low-power VLSI implementation of the Viterbi decoder (VD). A new precomputational scheme applied to the trellis butterflies calculation is presented. The proposed scheme is implemented in a 16-state, rate 1/3 VD. Gate-level power verification indicates that the proposed design reduces the power dissipated by the original trellis butterflies calculation by 42%.
