Convolutional Codes Decoding: The Viterbi Algorithm

An intuitive explanation of the decoding of convolutional codes (soft decision or hard decision) using the Viterbi Algorithm. Note the error committed for the Viterbi example considered at 11:21. The encoder structure must be of the type that considered at 01:26 in the previous video (Types of representation of convolutional codes). Otherwise, the Trellis and the entire procedure and analysis of decoding using Viterbi algorithm is perfect. :-)
