The trellis diagram of a rate 1/2 constraint length of 3 convolutional code is shown in Fig 3. The all-zero sequence is transmitted, and the received sequence is 100010000. Using the Viterbi algorithm, compute the decoded sequence.

Step 1
Initialize the path metrics for the two states (00 and 01) at time t=0. Since the all-zero sequence is transmitted, the initial state is 00, and its path metric is 0. The other state, 01, has an infinite path metric since it is not possible to start from that Show more…

The known sequence x(n)={1, 2, 3, 4}, n=0:3, completes the following calculations: (1) x(n) ⊗ x(n) [take the circumferential convolution length N=5] (2) x(n) ⊗ x(n) [take the circumferential convolution length N=7] (3) x(n) * x(n) (4) Write the step of calculating the circular convolution using the DFT method.
