If you lack these, consider first reading a more introductory text (e.g., Modern Digital and Analog Communication Systems by Lathi) before tackling Barry.

If a signal is corrupted by Additive White Gaussian Noise (AWGN), how does a receiver make the best guess? Barry introduces the and the Viterbi Algorithm . Rather than making symbol-by-symbol decisions (which can lead to error propagation), the Viterbi algorithm looks at the whole path of the signal to find the most likely sequence of bits. This is the mathematical engine behind technologies like convolutional codes and trellis-coded modulation. digital communication john r. barry pdf
