I am using the first edition of this book in my Telecommunication Engineering course. The author deserves my congratulations. This book is well organized, has clear explanations and makes an efficient compilation of the ITU-R recommendations, pointing precisely the relevant aspects when necessary. The book has also a practical focus, clearly showing real world and market experience, not only laboratory developed knowledge, still keeping well balanced level of math. This second edition certainly improves the already well-done work. I recommend it.
