Abstract


In digital communication system, channel coding techniques are mostly use convolutional codes for wireless Applications. For decoding the convolutional codes Viterbi decoder is commonly used, because of its high speed performance. Because of fast developments in the communication systems have generated in increasing demand for high speed and low power Viterbi decoders with long battery life, low power dissipation and low weight. In an Asynchronous Technique various Handshaking signals are used to communicate between blocks. Hence asynchronous designs are inherently data driven and are active only when doing useful work, enabling considerable saving in power and operating at the average speed of all components. The Proposed method is focused on the design of low power consumption of a Viterbi decoder for rate of r=1/2, with a constraint length K=3 by using asynchronous technique. This design will be implemented in Virtex7 field Programmable Gate Array (FPGA) kit.
