Current and future mobile terminals become increasingly complex because they have to deal with a variety of frequency bands and communication standards. Achieving multibandmultimode functionality (3G and beyond) is especially challenging for the RF-transceiver section. This volume presents cutting-edge physical layer technologies for multi-mode wireless RF transceivers, specifically RF, analog, and mixed-signal and digital circuits and architectures. Providing the most comprehensive treatment of this topic available, it features original contributions from distinguished researchers and professionals from both academia and industry, who anticipate the major trends and needs of future wireless system developments.
