Signal processing is used everywhere. It has applications in radar automotive applications, wireless and multimedia communication, electric power quality, landmine detection, vibration analysis, and physiological signals analysis. In the following, you will see what Chalmers University of Technology researches in this exciting field.
Department of Signals and Systems is one of 16 departments at Chalmers University of Technology. The department has 12 Research groups as shown in the table below. They are all located at the E-building of Chalmers.

Signal processing research group at the Department of in Chalmers aims to develop and analyze new algorithms. A strong base in statistical model-based signal processing allows the group to deal with classical problems of parameter estimation, detection, and object recognition. Its research has both interdisciplinary and application-oriented components. For example, there are researches in signal processing techniques applied to Pediatric Intensive Care for finding ways to predict cerebral ischemia and asphyxia. Another example is the research of modeling the way that train structures are borne to sound and vibrations propagate to find an optimal bogie design. The signal processing techniques are applied to medical and mechanical applications in these examples.
Signal processing research group received large funding from government, foundations, and Swedish companies such as Ericsson and Volvo. In addition, it has a lot of cooperation with other universities and research laboratories over the world. The considerate funding, the strong research atmosphere, and diverse cooperation with other research teams worldwide allow the group to produce excellent research results.

The research group has a great breakthrough in channel prediction and modeling for wireless communication. Due to the wireless environment, the strength of the signal is attenuated during transmission. Before 2000, the researches in combating deep fading of signal strength mainly focus on how to enhance the signal power. However, no researchers think that there are other ways to solve the problem. Researchers in the Signal processing group have an idea to compensate the deep fading by using channel prediction. After years of work, their algorithms are able to predict the wireless channel better than any existing methods. The accurate estimation of the channel allows the signal to be sent in a way that can combat fading well but with low power and complexity.
There are many interesting researches and applications of signal processing for people to explore. The fruitful results will improve our lives and Chalmers is striving for that.
