Prof. Walid Y. Ali-Ahmad, Mediatek Inc., Singapore Bio: Walid Y. Ali-Ahmad is currently a Senior Technical Director and RF Lead in the RF division of Mediatek Inc.; he has been with Mediatek since Oct 2007, and is currently involved in LTE and LTE-Advanced RFIC systems and advanced radio architectures development. His system design work led to the successful development of Mediatek’s family of low cost 3G/HSPA+ multi-band transceiver chipsets which are currently in mass production for low-cost 3G Smart Phones. Prior to Mediatek, between September’04 and September’07, he was an associate professor in ECE department at the American University of Beirut, with teaching focus on applied electromagnetic and RF systems and circuits. Between June’97 and September’04, he was a Principal Member of Technical Staff at Maxim Integrated Products, Sunnyvale, CA, in the wireless communications division, where he led the architecture and system design of the first direct-conversion radios for broadband CDMA Wireless Local Loop systems and for WCDMA cellular handsets. His first job after graduate school was as microwave design engineer at Anritsu company developing high-dynamic receivers for ATE systems. He received his Ph.D. in Electrical Engineering from the University of Michigan, Ann Arbor in December 1993, and his B. E. in Electrical Engineering with distinction from the American University of Beirut in June 1988. He is a Senior IEEE member and on the steering and TPC committee of the IEEE RFIC conference. He has given several invited talks at different IEEE workshops in the area of cellular transceivers system design and high-frequency radio development. Dr. Ali-Ahmad holds two patents in the area of RF design and has more than 40 publications in conferences, journals, and technical magazines. |

The growing demand for increased data rates and the surging volume of data traffic volumes have been behind the main push for the evolving 3GPP cellular standards, in order to meet those stringent network demands. To meet those demands, the user equipment (UE) will need to evolve in the future to support the different HSPA configurations required, such as: Rel-8 DC-HSDPA, Rel-9 extensions of DC-HSDPA operation together with dual-band or MIMO, Rel-9 DC-HSUPA, Rel-10 LTE or 4C-HSDPA with MIMO, and ultimately, LTE with carrier aggregation (LTE-A) in Rel-11 and beyond. This presentation will focus on the architectural and system challenges which future evolved UE configurations will impose on the multi-mode multi-band cellular transceivers integration goal.
