The Electrical and Computer Engineering research programme covers a wide range of areas:
- Communication Systems: Human beings have a fundamental need to communicate, and communication systems play an increasing role in our society. Over the past 10–15 years, the Internet and new wireless communication technologies have changed the very foundation for the way we interact. In the communication systems group, the research focuses on wireless communication networks and technologies for wireless communication units. This includes research topics like wireless sensor networks, cognitive radios, Internet of things and smart grids.
- Electronics and Biomedical Technology: The research in electronics is currently divided into two main areas focusing on integrated circuits and biomedical technology, respectively. Integrated circuits are microchips, and are vital components in the majority of modern electronic products. Examples of products are PDAs and Smartphones which continue to require higher performance combined with lower power consumption. The integrated circuit research group works with the design of advanced microchips with focus on low energy consumption, low voltage and high performance for both known and new applications, e.g. within biomedical and wireless communication systems.
- Biomedical technology is a cross-disciplinary field that integrates aspects of engineering science, medicine and biology. The research is oriented towards the applied technology and typically aims at the development of new and improved methods for treatment, monitoring and diagnosis with focus on new intelligent medical devices and equipment. Important engineering disciplines in this area include electronic instrumentation, sensor technology and digital signal processing.
- Embedded Systems: With the increase in consumer electronics, the need for embedded software to control and manage these units and systems is growing significantly. Examples are embedded software incorporated into all the wireless and portable devices with which we surround ourselves in the modern world, and embedded software that links the physical and digital worlds through systems of sensors connected in networks to form distributed real-time systems. The embedded systems research group focus on the development of reliable and maintenance-friendly real-time systems, software and hardware co-design techniques with special focus on the design of microcontrollers, microprocessors and systems on programmable chips.
- Signal Processing: The purpose of modern signal processing is to analyse, manipulate and present information in a manner suitable for communication and interaction between people. The basic challenge for researchers in this field is to extract meaningful information from signals with the aid of mathematical modelling, and then to transform this information into electronic units and computer-based systems that can be used by people. Research in the signal processing group is focusing on computer vision, audio processing and signal estimation.
- Software Engineering: Software systems play a decisive role in the modern knowledge-based society. An example is system software used in telecommunication systems to handle the millions of concurrent telephone calls and data transmissions. These types of software systems are built upon a number of well-established engineering principles and mathematical modelling. The software engineering group works with model-based approaches to the development of complex systems and critical software that require a high degree of operational dependability, control and reliability. Examples of application fields include software solutions for space, aviation, wind turbine or military equipment industry.
- Photonics: The use of light (photons) in technology is growing significantly in these years. Examples are the use of lasers and optical fibers in telecommunication and sensors for monitoring based on light. The photonics group’s research includes topics like optoelectronics, optical sensors and fiber optics.
