Average Reviews:
(More customer reviews)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.

A study of OFDM, including a comparison with other forms of single carrier modulation methods. It provides the design guidelines needed to maximise benefits from this technology. There is practical advice on how to plan, design and use OFDM to make wireless multimedia communications happen. It offers a solid base for assessing the performance of wireless OFDM systems; explains how OFDM signals are formed using the Inverse Fast Fourier Transform, how the cyclic extension mitigates the effects of modulation, and how windowing can limit out-of-band radiation; discusses the sensitivity of OFDM to synchronization errors; examines the basics of direct sequence and frequency hopping CMDA, helpful in understanding combinations of OFDM and CDMA; explains Multicarrier CDMA, various transmitter architectures, and the pros and cons compared to other CDMA techniques; and includes a discussion of the combination of OFDM and frequency hopping CDMA to get a multiple access system with similar advantages to direct sequence CDMA.
