3.1 Redo the Trellis of a convolution channel with memory one, 3 information Bits, known start and stop s0=s4=1 and BPSK (si{1,+1}) as in class, however with other weights instead of 1 and 2 , and a different received word. (Pick both yourself). 3.2 Compute the state diagram for a channel with memory 2. I.e., with h0,h1, and h2. Pick the values again by yourself. 3.3. What is the complexity for QPSK and memory 3? How many links do you then have between the layers..
