1. Overview UCB’s Department of EECS is generally ranked as one of the top EECS departments in the world. The department has 1,042 majors in the College of Engineering, 244 Computer Science majors in Letters and Science,and 524 graduate students. In addition, virtually all undergraduates at UC Berkeley pass through one of our classes at some time during their career.
2. Need and Opportunity We are in the final stages of planning an EECS Wireless Foundations center, dedicated to providing the theoretical and algorithmic foundations for tomorrow’s wireless systems. It will be tightly coupled with an instructional component in communication, fundamental RF system design and simulation, and wireless MEMs and devices. Some of the topics to be covered include propagation and antennas, low power systems, signal processing techniques and implementation, modulation and coding, network architectures, software and protocol performance, sensor and ad-hoc networks, and network security.
We believe that tomorrow's wireless environment will consist of heterogeneous systems operating at many scales. Many of these systems will be distributed, mobile, and some will incorporate low power, unreliable, and computationally limited components. The number of different wireless systems competing for the use of scarce spectrum will continue to proliferate with different services having distinct quality of service requirements.
Yesterday's theory and algorithms are not adequate to address this:
Architectures have been primarily driven by a "point-to-point" philosophy -> we need to better understand a network viewpoint wherein nodes can cooperate intelligently taking advantage of the special properties inherent in wireless communication.
Architectures have been primarily centralized -> we need to develop highly distributed architectures and algorithms that are still robust and energy-efficient on a system basis.
Current wireless systems share spectrum through a rigid frequency partition and tight regulatory requirements -> we need more flexible and adaptive spectrum sharing mechanisms that can mostly be self-enforced at the level of the wireless nodes themselves.
Research efforts have been primarily compartmentalized -> we need highly inter-disciplinary research across signal processing, communications, game theory, and networking.
If these are not done soon, we run the risk of having innovation in the future being hobbled by well intentioned but misguided regulatory regimes and legacy systems put in place today.
Our research focuses on getting fundamental insights and developing better ways to think about wireless systems. In the course of doing this, we come up against many previously formulated open problems in network information theory (e.g. non-degraded broadcast channels, relay channels, two-way channels, etc.) that have evaded the community's grasp. We believe that by taking a fresh perspective and formulating the problems in a different way, it is possible to get further understanding. In addition to information theoretic models and bounds, we study protocols, codes, and algorithms. Some topics we are currently exploring are:
Understanding the 3 R's of spectrum management: spectrum reduce, reuse, and recycling.
Intelligent cooperation between nodes to serve network functions
Understanding the power of feedback and common protocols in enabling spectral efficiency at the network level.
Distributed signal processing for sensor networks.
Exploitation of mobility and ultra wideband to communicate.
Understanding what "quality of service" means for wireless systems.
Fundamentally rethinking the architecture of multimedia-over-wireless systems.
3.Commitment by University We have an excellent professional instructional and research staff that ably administers and maintains our laboratories and have committed infrastructure funds for the center and lab , to be located in Cory Hall.
Expected users, course(s) covered and numbers of students per academic year: Our students are given a lot of freedom to formulate problems and plans of attack on their own, though the faculty advisors are certainly always available to share ideas and brainstorm with the students. Most of the faculties meet with their students at least once a week, and many students also collaborate with each other on at least some of their research. While doing research is certainly the core part of the student experience here, the following classes will also be served by this grant:
EECS117: Electromagnetic Fields and Waves
EECS217: Microwave Circuit Design
EECS221A: Linear Systems
EECS226A: Stochastic Processes, Estimation, and Detection
EECS224: Digital Communications
EECS225x: Signal Processing
EECS229: Information Theory
EECS290-X: Special Topics Courses on Coding Theory, Wireless, and other advanced topics
Location where equipment will be placed: In addition to the Wireless Foundation center on the second floor of Cory Hall, we plan to renovate and combine instrumentation labs with PCs used in design and simulation. We also plan to build an anechoic chamber for use by the students for antenna experiments.
Applications: In addition to RF design and simulation tools such as ADS, we plan to run significantly compute-intensive custom algorithms and simulations.
The Ipaq and Tablet PCs will be a testbed for the development of multimedia applications on the wireless infrastructure landscape.

4.1A Specific Project: BASiCS The BASiCS group is involved in a number of research projects:
Low Complexity Video Encoding: We are in the process of developing a novel video coder, which directly addresses the problem of uplink video in wireless wide-area networks. The coding scheme enables low complexity encoding and decoding by pushing most of the computational complexity to the network. It is also more tolerant to channel losses as compared to standard video codecs. (Details below).
Distributed Multimedia Transmission from Multiple Servers: We have developed an algorithm to deliver near-constant quality of video by parallel streaming from multiple servers.
Distributed Audio Processing: We address the problem of distributed compression of audio sources for the purposes of acoustic beamforming, speaker location and tracking, blind source separation, 3D sound field capture, etc.
Sensor Networks: We are working on algorithms for reducing energy consumption in sensor networks using distributed adaptive signal processing algorithms. The algorithms track and exploit relevant correlation structures of the network.
Secure Hashing and Authentication for Image databases: We are developing scalable algorithms for indexing very large image databases which are robust to malicious attacks on the databases as well as to unauthorized users.
4.1B Specific Project: BEAR The BErkeley AeRobot (BEAR) project is a research effort started in 1996 that
encompasses the disciplines of hybrid systems theory, navigation, control, computer vision, networked communication, discrete decision making under uncertainty, coordinated mission planning and and reinforcement learning. The BEAR vehicle fleet is currently composed of autonomous helicopters (Yamaha and Kyosho radio-control helicopter airframes) and all-terrain vehicles (ActiVision Pioneer ground robots), all equipped with GPS/INS, cameras, on-board real-time controllers and a range of sensors.
In the BEAR project, unmanned air vehicle (UAV) navigation sensors are based on an integrated INS/GPS and integrated position and attitude sensors, embedded
real-time flight controllers and auxiliary computing systems, wireless communication, and vision capabilities, allowing the UAV to achieve autonomous flight by following dynamically uploaded commands from an external souce. The flight control system is capable of performing autonomous hover, turns, nose-in maneuvers, forward flight and longitudinal-lateral flight with fixed headings.
