Viterbi algorithm is employed in wireless communication to decode the convolutional codes; those codes are used in every robust digital communication systems. Such decoders are complex and dissipate large amount of power. Thus, the paper presents the design of an Adaptive Viterbi Decoder (AVD) that uses survivor path with parameters for wireless communication in an attempt to reduce the power and cost and at the same time increase in-speed. Most of the research paper to reduce power consumption or work with high frequency for using the decoder in the modern applications such as 3 GPP, DVB and wireless communications.
