Reviews I'm not sure how anybody who has read a book about OFDM can then claim that they don't understand how it deals with multipath. OFDM is designed specifically to deal with multipath so I doubt whether he/she has actually read this book properly. Also, the IFFT is a fundamental part of OFDM and if you don't understand this then you won't understand much else. I have not read the book but I have read papers by Ramjee Prasad and I don't believe that they have described OFDM so badly that a reader does not understand the basics concepts.
Actually, now I have read it I can confirm that it does describe how OFDM deals with multipath. I would not say this is a particularly good book though. It is very short, especially for the price. There is so much research out there on OFDM and multicarrier CDMA that that you would expect a fair number of topics to be covered but it seems only the basics are covered and what's more this book is mainly just about the authors own research areas. For example, Prasad has published work on some variant of OFDM or MC-CDMA (I can't remember what it was because I borrowed the book from a library but I do know that this hasn't received much attention so I imagine it can't be that good) and there is a large proportion of the book on this and other topics that I wouldn't have expected to be covered when there is so much other material that could have been presented. This is unfortunate because there needs to be a decent OFDM book available (compare with the number of CDMA books out at the moment) and I have heard that the only other one isn't much better than this one. All in all, if you're after useful OFDM or MC-CDMA material you only get about 40 or so pages worth. My advice would be to buy the other book if you have to have an OFDM book or if you have access to research papers stick to them ahead of buying this book. For example, if you are after material on MC-CDMA or its variants you won't learn anything (or very little) if you have read "Overview of Multicarrier CDMA" by Hara & Prasad.
