7.13. Using sequential decoding, illustrate the path along the tree diagram shown in Figure 7.22 when the received sequence is 011100011 1. The backup criterion is three disagreements. 7.14. Repeat the decoding example of Problem 7.13 using feedback decoding, with a look- ahead length of 3. In the event of a tie, select the upper half of the tree. Input o Output + Figure P7.5 7.13.
