"... I read through many articles, books and videos but never got the whole picture. Your book really helped me understand the crux of the subject matter. Throughout the book, simple analogies are used to explain difficult concepts that makes it an easy read. There are plenty of resources explaining the "What" and the "How" part of the 5G-PHY, but this is the only book that explains the "Why" part, i.e. why things are done in a certain way. Thank you from the bottom of my heart."
