Abstract

In this paper we present about implementation of channel coder and Viterbi decoder for Mobile communication & IEEE 802.11a Wireless LAN. In the IEEE 802.11a Wireless LAN decoding provided that Viterbi algorithm and convolutional encoder by constraint k=7, ($133_8,\;171_8$) for channel error correction. This Paper presents a novel survivor memory management and decoding techniques with sequential backward state transition control in the trace-back Viterbi decoder, In order to verification we provide to the examples of circuit design and decoding results.
