Andreas F. Molisch

Abstract: Wireless multiple-input - multiple-output (MIMO) systems, defined as systems that have multiple antenna elements at both link ends, can greatly enhance the robustness and spectral efficiency of wireless communications. While most of the literature has concentrated on signal processing and space-time coding for MIMO, the fundamental performance limits are determined by the propagation channel and the way it is "excited" and "sampled" by the transmit and receive antenna arrays, respectively. In this talk, we first give an overview of array design, in particular, the question of how close we can space antennas. Subsequently, we describe typical propagation channels and how they impact system capacity; we also consider ways to describe the interaction between antennas and channels. Throughout the talk, we will show how the antenna and channel properties impact system capacity, diversity, and other system performance parameters.

Mario Gerla

Title: Peer to Peer Urban Sensing from Mobile Platforms

Abstract: There has been growing interest in urban surveillance using vehicles that monitor the environment, classify the events, e.g., license plate reading, and exchange metadata with neighbors in a peer-to-peer fashion. The idea is to create a totally distributed index of all the events, to be accessed by users. For instance, the Department of Transportation extracts traffic congestion statistics; the Department of Health monitors pollutants, and; the Police carries out forensic investigations. Mobile, vehicular sensing differs significantly from fixed (wireless) sensing. The vehicles have no strict limits on battery life, processing power and storage capabilities. Moreover they can generate an enormous volume of data, making current sensor harvesting solutions inadequate. The talk describes MobEyes, a middleware solution that diffuses data summaries to create a distributed index of the massive sensed data base. We discuss the challenges of designing and maintain such a system, from information dissemination to harvesting, routing and security.

Title: Adaptation, coordination and distributed resource allocation in interference-limited wireless networks

Abstract: A sensible design of wireless networks involves striking a good balance between an aggressive reuse of the spectral resource throughout the network and managing the resulting co-channel interference. Traditionally this problem has been tackled using a "dive and conquer" approach. The latter consists of deploying the network with a static or semi-dynamic pattern of resource reutilization. The chosen reuse factor, while sacrificing a substantial amount of efficiency, brings the interference to a tolerable level. The resource can then be managed in each cell so as to optimize the per cell capacity, using advanced air interface design.

In this talk we focus our attention on the overall network capacity as a measure of system performance. We consider the problem of resource allocation and adaptive transmission in multicell scenarios. As a key instance, the problem of joint scheduling and power control simultaneously in multiple transmit-receive links, which employ capacity-achieving adaptive codes, is studied. In principle, the solution of such an optimization hinges on tough issues such as the computational complexity and the requirement for heavy receiver-to-transmitter feedback and, for cellular networks, cell-to-cell channel state information (CSI) signaling. We give asymptotic properties pertaining to rate-maximizing power control and scheduling in multicell networks. We then present some promising leads for substantial complexity and signaling reduction via the use of newly developed distributed and game theoretic techniques.

Hans Martin Ritt
Title: Development of complex wireless systems requires new development technologies

Abstract: Developers of signal processing and communication systems are facing a constantly increasing demand for more complex and powerful products that need to be developed in very short time frames. Some industry watchers have predicted an upcoming "productivity crisis" for the implementation of signal processing and other embedded systems in programmable logic or software, respectively. However, they often take a crisis view based on an incorrect measurement: the number of lines of code that an engineer can write in a day. This measure does not take into account the level of programming abstraction. Based on the technological evolution of the hardware combined with new ways to develop software, there have been always architectural and algorithmic improvements that create breakthrough performance advances. Each of these advances was made possible by new development tools that addressed the critical problems of the day.

Mastering the design of computationally intensive signal processing systems calls for a development environment that lets designers accurately model and simulate the behavior of an entire system, including the interaction of hardware and software subsystems as well as the environment in which the system must operate. Traditional procedural programming and hardware description languages and incremental extensions to those languages are not appropriate for modeling this level of algorithmic complexity. For decades, standard specifications, textbooks and engineers' whiteboards have used block diagrams to specify signal flow, timing and system architecture. It is not surprising, therefore, that graphical modeling tools are the natural way to specify, design and verify such signal processing systems.

At The MathWorks he is holding the position of a Principal Application Engineer and a team leader covering a broad spectrum of applications based on the Model-Based design approach starting from the design of control systems in the automotive industry to signal processing systems in the communication industry. He manages a team of application engineers with more specific focus.
