'Li, Wu and Laroia's book fulfils a major need - an authoritative reference on OFDMA, which is the foundation for 4G cellular technology, and likely the dominant air interface technology for many years to come. The authors are renowned innovators and system engineers who among them pioneered the use of OFDM for cellular systems, and the book contains many crisp insights that no other team of authors could provide. The academic rigor of the book is also remarkable, particularly from practising system engineers. In fact, they have independently derived several cutting edge research results in order to make various technical points! A must-have book for any wireless system engineer's personal library.'
