High speed low power viterbi decoders for trellis code modulation is well known for the delay consumption in underwater communication. In transmission system wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. WiMAX is the wireless communication standard designed to provide 30 to 40 Mega bits per second data rates. WiMAX as a standards based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL. WiMAX can provide at home or mobile internet access across whole cities or countries. The address generation of WiMAX is carried out by interleaver and deinterleaver. Interleaving is used to overcome correlated channel noise such as burst error or fading. The interleaver/deinterleaver rearranges input data such that consecutive data are spaced apart. The interleaved memory is to improve the speed of access to memory. The viterbi technique reduces the bit error rate and delay using wimax.
