Different Approaches For Implementation of Viterbi decoder on reconfigurable platform

Generally, the data transmitted over any communication channel is affected due to noise. So, for detecting and correcting the errors due to channel noise, encoding and decoding should be performed at the transmitter and receiver end respectively. The Viterbi algorithm is used in many communication channels for decoding convolutional codes. Using VLSI technology, the system requires low power, less area and high speed constraints while designing. Because of different steps for designing Viterbi Decoder speed of designing is limited. In this paper, different kind of implementation of Viterbi decoder along with their performance has been discussed.
