Convolution Encoder, Viterbi Decoder


In the present scenarios, data transferring between the systems plays a vital role as the technologies are increasing day-by-day the number of users is simultaneously increasing. This wide usage leads to major issues in the digital communication systems and results in data corruptions. It's very necessary for the telecommunication to reduce the data corruption by providing a suitable solution to the errors occurred in the communication process. One such method that decodes the process by simultaneously correcting the process effectively is Viterbi algorithm. For decoding the convolution codes Viterbi algorithm is the highest recognizable algorithm. This algorithm may be described with software as well as hardware implementations. To engage well organized communications an efficient data is presented by the digital systems. Data corruptions are the important issue confronted by the digital communication systems. To decrease data corruptions error correcting codes is a best technique. Al most all communication systems followed it because it's power to decode efficiently, even Viterbi algorithm needs very typical hardware. While the decoding operation is in advance, the functioning obstructions can be eliminated, So that an improved method, Adaptive Viterbi Algorithm is used. The decoding of codes can be done very fast, as this algorithm is very effective in high speed functions. Convolution codes are used to gain a possible code sequences AVA uses maximum –likelihood decoding process.
