Viterbi decoder is used for decoding data encoded using Convolution Forward

Error Correction codes or data that suffers inter-symbol interference. They occur in a

large proportion of digital transmission. Viterbi decoders employed in digital wireless

communications are complex and dissipate large power. The proposed method focuses on

Gate diffusion input (GDI) which is a low power technique of digital circuit design.

Dynamic component of power is reduced in GDI technique as source of PMOS is not

permanently connected to Vdd.-Viterbi decoder is used for decoding data encoded using Convolution Forward
