The convolutional code of Problem 8.1 is used for transmission over an AWGN channel with hard decision decoding. The output of the demodulator detector is (101001011110111 ··· ). Using the Viterbi algorithm, find the transmitted sequence, assuming that the convolutional code is terminated at the zero state.
