Read MoreConstraint length of the Convolutional Code
Convolutional CodesConvolutional codes are error correcting codes where the data streams of indefinite lengths are encoded before transmission over noisy channels. The message streams are encoded by the sliding application of Boolean functions that generate a sequence of output bits.Convolutional codes were first introduced in 1955, by Elias. After that, there were many interim researches by many mathematicians. In 1973, Viterbi developed an algorithm for maximum likelihood decoding scheme, called Viterbi scheme that lead to modern convolutional codes.Parameters in Convolutional CodesFor generating a convolutional code, the information is passed sequentially through a linear finite-state shift register. The shift register comprises ...
