Institute for Theoretical Information Technology

Network Design, Control & Optimization

Introduction

The request for wireless services, particularly, for ubiquitous mobile internet access and multimedia connections, has drastically increased over the last years. Accordingly, the capacity of wireless networks needs to be continuously enhanced subject to a strictly limited available radio spectrum. To achieve this goal, accurate planning and deployment, continuous optimization, and efficient resource allocation are of tremendous importance. Sophisticated analytical models and methods from communications engineering, information technology, mathematics, optimization, and computer science are combined to find solutions to the challenging problems.

Topics

The Institute for Theoretical Information Technology contributes to planning, optimizing, and operating wireless (sensor) networks. In particular the following topics are investigated.

• Field strength prediction provides realistic input data.
• Semi-stochastic MIMO channel model closes the gap between deterministic and stochastic models.
• Adequate Network Planning is beneficial for
• Self-organized network operation.
• Moreover, cooperative wireless sensor networks are investigated.

As OFDM systems are predominating in modern mobile communication systems, particular investigations on OFDM systems are presented in a section of its own.
