Response to the following problem:
A recursive systematic convolutional code is characterized by
G(D) = [1 1/D+1]
This code is used with antipodal signaling with εc = ±1 over an additive white Gaussian noise channel with noise power spectral density of N0/2 = 2 W/Hz. It is assumed that the convolutional code is terminated at the zero state and the received sequence is given by
r = (0.3, 0.2, 1, -1.2, 1.21.7, 0.3 - 0.6)
1. Use the BCJR algorithm to determine the information sequence u.
2. Use the Viterbi algorithm to determine the information sequence u.
