Current and future mobile terminals become increasingly complex because they have
to deal with a variety of frequency bands and communication standards. Achieving
multi-band/multi-mode functionality is especially challenging for the radio frequency
(RF)-transceiver section, due to limitations in terms of frequency-agile RF components
that meet the demanding cellular performance criteria at costs that are attractive
for mass-market applications. The focus of this volume is on novel transceiver concepts
for multi-mode/multi-band cellular systems from the antenna to baseband.
One approach is based on the integration of digital signal processing capabilities
implemented locally on the RF integrated circuit. The utilization of digital signal
processing capabilities is in line with the ongoing trend toward minimum-featuresized
RF-CMOS in the cellular market, which makes it extremely attractive in terms
of flexibility, power consumption, and costs. Moreover, advances in the field of antennas,
RF-front-end modules and novel analog signal processing architectures are
covered to give a consolidated outlook on future concepts for cellular radios.
This volume summarizes cutting-edge physical-layer technologies for multi-mode
wireless RF transceivers, specifically RF, analog, and digital circuits and architectures,
anticipating the major trends and needs of the future wireless system developments.
Firsthand materials from distinguished researchers and professionals from
both academia and industry are collected. Furthermore, this volume offers a comprehensive
treatment of the topic, presenting state-of-the-art technologies and insight
covering all the essential transceiver building blocks to be used in future multi-mode
(third generation and beyond) wireless communication systems.
