Professor Eltawil’s Research
The current research interests of Dr. Ahmed are in the general area of low-power digital circuit and signal processing architectures with an emphasis on mobile systems. He is affiliated with both the Center for Pervasive Communications and Computing (CPCC) and the Center for Embedded and Cyber-Physical Systems (CECS) at the University of California, Irvine.
In the field of wireless communications, two seemingly diverging trends can be discerned. The first trend is concerned with broadband wireless communication which is flourishing driven by the ever increasing need for higher bandwidth to satisfy multimedia networking. The second trend is related to low bit rate, ultra low power applications, which are finding numerous applications, such as remote wireless sensing, wearable electronics, etc. At WSCL, our program is architected to identify and research technologies that provide the foundation on which ground breaking innovations capable of serving this wide spectrum of challenges can be conceived, designed and tested.

The WSCL group is led by Dr. Ahmed Eltawil. The research focus of the group lies in the area of efficient architectures for communications systems in general and wireless systems in particular. Specifically, we employ a multidisciplinary approach to the design and development of communication systems including but not limited to:
- Design of system and VLSI architectures for broadband wireless communication.
- Highly programmable and versatile ASIC/FPGA architectures for high speed data communications.
- Physical layer communication system design including system architecture and partitioning, cross layer optimizations, and physical mapping to hardware.
- Implementations and architectures for efficient digital signal processing.
- Digital circuit development including low power design and yield estimation.
- Power management for wireless and multimedia applications.
- Cross-layer power management approaches to manage design margins and process variation effects in highly scaled technologies.
- Focus on low power error tolerant cache and memory system architectures.
- Low power VLSI architectures for key building blocks such as:
- Sphere decoding for MIMO systems, Programmable FEC cores, Channel estimation etc.
- Full duplex communications
- Rx and Tx transmit and receive at the same time in the same band while actively managing interference via analog and digital cancellation techniques.
- Managing interference limited networks
- Architecture an system level approaches for managing interference in cellular networks.
- Wireless sensor networks applications such as distributed estimation of unknown random vectors incorporating relays and fusion centers.
- Optimal relaying techniques under both transmit and receive power constraints for MIMO systems.
- Nonlinear power amplifier effects and analysis
- Source localization for brain ECoG waveforms
- Low power body area networking
