Figure 5: Trellis diagrams, in this case for the K=3 (7, 5) convolutional encoder, represent the linear time sequencing of events. Decoder; The Viterbi algorithm is based on the Maximum-Likelihood ...

You can easily implement this type of encoder in any reconfigurable architecture. The polynomial generators are g1=1+X+X 2; g2=1+X 2. Hard-decision Viterbi decoding. The first step in the ...
