Title: A lot of formulas, very little insight
Review: The author has, maybe, good knowledge of the material, but little contact with reality. A lot of formulas, piled up, offer practically no insight. Contrast this with the book of Sklar, "Digital Communciations". Proakis offers a fake "advanced" mathematical level, that might impress an ignorant beginning graduate student, but removes any chance of understanding the material because of the plethora of useless pictures, formulas and words.The material of the book could have been presented in a quarter of the space. It is hard to imagine a poorer writing style.
