Power Efficiency in Broadband Wireless Communications focuses on
the improvement of power efficiency in wireless communication
systems, especially of mobile devices. Reviewing cutting-edge
techniques for conserving power and boosting power efficiency, the
book examines various technologies and their impact on consumer
devices. It considers each technology, first by introducing the
main physical layer components in recent wireless communication
systems along with their shortcomings, and then proposing solutions
for overcoming these shortcomings. The book covers orthogonal
frequency division multiplexing (OFDM) signal generation and
formulation and examines the advantages and disadvantages of OFDM
systems compared to alternative multiplexing. It introduces one of
the main drawbacks of OFDM systems, peak-to-average power ratio
(PAPR), and discusses several PAPR techniques. It also explains how
to overcome the main drawbacks of real-world OFDM system
applications. Considers power amplifier linearization for
increasing power efficiency and reducing system costs and power
dissipation Describes the implementation scenario of the most
promising linearization technique, digital predistortion Presents
some experimental demonstrations of digital predistortion when the
device under test is in the loop Because the most costly device in
a communication system that has a direct impact on power efficiency
and power consumption is the power amplifier, the book details the
behavior and characteristics of different classes of power
amplifiers. Describing the evolution of the mobile cellular
communication system, it details a cost-effective technique to help
you increase power efficiency, reduce system costs, and prolong
battery life in next generation mobile devices.
