van Nee was among those who proposed the OFDM-based physical layer, which was selected for standardization in IEEE 80. 1, MMAC, and ETSI HiperLAN. Ramjee Prasad is Wireless Information and Multimedia Chair and Co-Director of the Center for Personkommunikation at Aalborg University. He is the author of CDMA for Wireless Personal Communications (Artech, 1996) and Universal Wireless Personal Communications (Artech, 1998). Dr. Prasad earned his P. in communications from the Birla Institute of Technology. Publisher: Artech House Publishers.

This is the first book to give a broad treatment to OFDM for mobile multimedia communications. Chapter 1 presents a general introduction to wireless broadband multimedia communication systems (WBMCS), multipath propagation, and the history of OFDM.

Although I coauthored OFDM for Wireless Multimedia Communications with Richard and Multicarrier Techniques for 4G Mobile Communications with Shinsuke, this book is very different in that it presents an overview of the wireless local area network (WLAN), wireless personal area network (WPAN), frequencydomain channel model, a novel hybrid OFDM concept, and a practical OFDM system.

If you are looking for a book that clearly explains the mysteries of OFDM and COFDM then, you will have to wait. This is not that book. Much is left to "as an exercise for the student." There is some generic stuff on coding but how it relates to multipath mitigation is not clear. There are no good pictures of spectrums. The effect of amplifier non-linearities is inadequately addressed. The concept of IFFT as applied to modulation is not explained in a way you can understand it quickly. The section on coherent and differential detection is uneven in the amount of detail and understandability. The whole book has in places either too much math or not enough. There is no section on performance that tells you what the end to performance might be. Good try but far from perfect.

Appreciate on time delivery and the meet my expectations. Thank you.

I suppose if you were already familiar with OFDM this book might be useful to you. It touches on most aspects of the modulation. However, this book is very poorly written. Throughout it introduces technical terms without defining them. For example in chapter 2 it talks about delay spread and cyclic prefixes with no description whatsoever of what those terms mean. Unless you already know the nature of an OFDM signal, the description is just a mish-mash of jargon. In a supposed numerical example, there is no math; just a rambling description of the math.

from page 47,

"The delay-spread requirement of 200ns suggests that 800ns is a safe value for the guard time. By choosing the OFDM symbol duration 6 times the guard time (4.8us), the guard time loss is made smaller than 1 dB. The subcarrier spacing is now the inverse of 4.8-0.8=4us which gives 250kHz. To determine the number of subcarriers needed, we can look at the ratio of the required bit rate and the OFDM symbol rate. To achieve 20Mbps, each OFDM symbol has to carry 96 bits of information (96/4.8us=20Mbps)......"

Prior to this "example" there is no justification, explanation, or even an equation that tells why the guard time should be 4 times the delay-spread. The same goes for the symbol time being 6 times the guard time. There is no explanation of guard time loss or why 1dB is good value for it. They don't even tell you that the requirement for subcarriers being orthogonal(the 'O' in OFDM) is that duration of the symbols and carrier spacing have a fixed mathematical relationship.

One really has to wonder what the point of this book is. It certainly wasn't written to teach the topic of the book.

Here's a note to technical book writers. Ask yourself who your audience is. Write assuming the reader is not as knowledgeable as you are. If they were, why would they need your book? The first time you use an important technical term clearly define it, or include a glossary. Have a knowledgeable peer proofread it and have someone from the target audience read it before publication. The authors of this book apparently did none of this.

Artech House, the folks that brought us poorly edited-or non-edited books bring you yet another example of self-referencing, poorly-written, cut and paste job. A very expensive one this time.

Of particular note is Chapter 5: Coherent and Differential Detection. Authors were busy copying and pasting covariance matrix entries but they forgot to check whether their equations for channel coefficients make sense. They dont.

In general, no attempt was made to provide insight. Self-advertisement, major errors, confused descriptions, pigeon English rule the land here. I wonder whether van Nee set up the organization of the book, and Prasad filled in the blanks, since the second author appears to be producing (I would not call that writing) too many books in a short time period. Where else, at Artech House of course.

Recommendation: Avoid.

OFDM is not a new technology. It was firstly introduced in 1960s. But until recently, OFDM was largely unknown. As OFDM seems to be the only technology for wideband wireless transmission, it became the past one year. OFDM was used in digital audio/video transmission, wireless LAN and is currently under investigation for wireless fixed point transmission. This is book is one of the only two books about OFDM available now, and I think it is a good book. It gives a quite complete overview about wireless transmission, and also addresses the main techniques used in OFDM, including sychronization, channel equalization, peak-average power problems, etc.. It is the right book for starting OFDM. The only shortcome of this book is that I found the references given were not enough.
