Wireless communication has grown from simple radio links into handsets that browse the web, stream video and handle e-commerce and e-mail. Reliable, fast transmission at hundreds of megabits per second over long distances is increasingly hard, because the wireless environment limits capacity and data rate. That pushes researchers towards user cooperation and the spatial dimension.
The group develops signal processing algorithms for speech and image processing, wireless sensor networks, analog and digital communication, radar and sonar. Alongside signal modelling, quantization, parameter estimation, sampling and signal representation, it explores less conventional directions such as fractal signals and chaotic behaviour in nonlinear dynamical systems, often taking inspiration from nature.
