About us

Optimization for Signal Processing and Communication (OSPAC) is a research group within the ECE Department at the University of Minnesota -- Twin Cities. At any point in time, OSPAC may consist of a number of visiting faculty members/students, postdoctoral researchers and full-time graduate students. We study various algorithmic, complexity and implementation issues in digital communication and signal processing. We are especially interested in the mathematical theory, design and analysis of efficient optimization algorithms that have strong motivations from real world applications. Our current research is focused on several aspects of signal processing and wireless communication networks, such as dynamic spectrum management, robust beamforming in multiuser MIMO systems, complexity analysis and linear transceiver design for interference alignment, matrix completion, compressed sensing, image recovery in MRI, and adaptive signal processing in hearing aids. 

OSPAC has extensive and strong cooperation with many government agencies and industry partners. Each year OSPAC students usually have opportunities to take summer internships in industrial research labs. In recent years, the research in OSPAC has been supported by the National Science Foundation (NSF), the Air Force Office of Scientific Research (AFOSR), the Army Research Office (ARO), Huawei Technologies Co., Ltd. and the ADC Endowed Chair Fund. We strongly encourage talented, hardworking and fun-loving students to join OSPAC. With its highly stimulating and dynamic atmosphere, OSPAC is a great place to have a first-class education and to launch your scientific career.
