Chiara Martelli,
Multi-Standard Low-Power Base-Band Digital Receiver, Enhanced for HSDPA.
2006; XIII, 180 pages. € 64,00. ISBN 3-86628-094-7


The most efficient use of wireless communications calls for different trade-offs for different applications in terms of air interface and implementation cost, thus different standards     must always coexist. Recent rapid expansion of wireless and the accompanying multitude of standards, however, make multi-mode or reconfigurable radio terminals a pressing need for users and industry alike. Therefore programmable design system topologies (DSP, FGPA) are now flourishing but unfortunately without consistently solving the problem of increasing power consumption and chip area utilization. The present contribution is the integration of a dedicated base-band digital front-end where different standards (GSM-EDGE/WCDMA/WLAN) coexist, and of a WCDMA/HSDPA signal processing part, for synchronization and data stream decoding. The core occupies 3.6mm$^2$ and consumes 0.4/47.7/17.2mW in GSM/WCDMA/WLAN mode.

Chiara Martelli received her M.S. degree in electrical engineering from the Alma Mater Studiorum, University of Bologna, Italy, in 2000, after having completed her diploma thesis at the Integrated Systems Laboratory (ISL), Swiss Federal Institute of Technology (ETH), Zurich. In 2001 she officially joined ISL as a research and teaching assistant, where she worked as digital designer for the analog and mixed-signal design group. Since 2006 she is a senior design engineer with Advanced Circuit Pursuit (ACP) AG, Zollikon.
