Signal Processing Research Laboratory

In the SPRL we develop groundbreaking signal processing algorithms that are applied in interdisciplinary areas such as biomedicine, communication systems and multimedia. The lab is equipped with 6 high speed workstations, 4 Xilinx Virtex-6 Xtreme DSP boards (ML-605), 5 Xilinx Vitrex-5 Xtreme DSP boards (ML-506). We also  have access to the College of Engineering high performance computer cluster for multi-core and multi-task computations.

Area of Research:

Digital and Statistical Signal Processing, Graph Signal Processing, Biomedical Signal Processing, Brain Connectivity Analysis, Applied Mathematics,
