Digitally reconfigurable radio transmitters for ubiquitous and cognitive wireless networks
EF 2007-08
Résumé
Software Defined Radio (SDR) and Cognitive Radio (CR) technologies are propelling wirelesscommunications by allowing seamless global service, interoperability and dynamic spectrum allocation. Thisproject aims at investigating flexible, practical and cost and power efficient Digital Reconfigurable Radio(D2R) front-end architectures that can be adaptively tuned to support a broad range of frequencies and airinterfaces through software programming. Since the transmitters' front-ends are generally the bottleneck ofevery radio system design, this project will mainly focus on the development of a novel cost effective andpower efficient integrated software/hardware reconfigurable polar transmitter. The architecture design taskshall first address issues such as optimum location of the Analog/Digital interface location, flexibility, powerconsumption and generic building blocks. These are assumed to be identified and their requirements derived.Another objective is to develop and fabricate high efficiency and switching mode reconfigurable poweramplifiers in order to minimize the power consumption of the D2R. To enable the implementation of suchswitched mode PAs, low-loss, multi-harmonic and reconfigurable load transformation networks, usingadvanced RF electronically tuneable devices, will be investigated. Advanced digital signal processing (DSP)techniques will also be developed for proper modeling and linearization of the nonlinearity exhibited byreconfigurable polar transmitters, in order to satisfy the stringent linearity requirements of the wirelesscommunication standards. In addition, sophisticated DSP techniques will be researched for dynamicreconfiguration of the analog circuitry of the digitally reconfigurable polar transmitter.This project will target wireless standards spanning from CDMA (3GPP-LTE) up to the most demandingOFDM based communication standards (802.11n, 802.16). Hence, a prototype, with carrier frequencies of upto 10GHz and modulation bandwidth of up to 20MHz, will be fabricated in order to assess the performance ofthe proposed digitally reconfigurable transmitter.
