• Flexible Wireless Communication Systems (FleCoS)
• Opportunistic wireless communication systems (UNICS)

BEAMFORMING AND RADIO RESOURCE MANAGEMENT IN CO-OPERATIVE WIRELESS NETWORKS (BeCON)

Description
The project considers opportunistic co-operative wireless networks. Particular emphasis is on linear beamforming and radio resource management theory, analysis and solutions. Both base station or infrastructure and user co-operation are considered. The objectives of the project include achieving deep theoretical understanding on the capacity of the co-operative wireless cellular networks, linear transmit/receive beamforming design and optimization, estimates of transceiver complexity, and design guidelines of heterogeneous wireless networks based on the co-operation paradigm.

The principal investigator of the project is Professor Markku Juntti.

Requirements
Good knowledge on wireless communications, elements of information theory and mathematical optimization theory is required.

To successfully occupy the position of a Doctoral Student, the applicant must possess an applicable Master of Science degree or an equivalent degree from a foreign institution of higher education.

FLEXIBLE WIRELESS COMMUNICATION SYSTEMS (FleCoS)

Description
The goal of this project is to develop a set of methodologies and along with protocols and transmission and reception strategies for cooperative and opportunistic wireless networks. The focus is on decentralised network topologies and operatorless radio access network concepts. We develop opportunistic and cooperative communication systems utilising i) different spatio-temporal approaches in a multi-user environment, ii) cross-layer optimisation and inter-cell interference reduction, iii) novel multiple input multiple output (MIMO) transmission schemes, iv) new methods of frequency usage and sharing for available and newly identified frequency spectrum, v) flexibility and reconfigurability of software-defined multi-antenna, multi-standard radio systems, vi) spectrum-agile radios and networks.

The principal investigator of the project is Behnaam Aazhang; Ph.D.; J.S. Abercrombie Professor and Chair, Department of Electrical and Computer Engineering, Rice University, Houston, Texas, USA and Finnish Distinguished Visiting Professor, CWC, University of Oulu, Oulu, Finland.

Requirements
Strong background in communication and information theory, strong fundamental knowledge of wireless communication and networks, along with basics of mathematics (optimization, linear algebra, probability, and analysis), signals and linear system theory.

To successfully occupy the position of a Doctoral Student, the applicant must possess an applicable Master of Science degree or an equivalent degree from a foreign institution of higher education.

OPPORTUNISTIC WIRELESS COMMUNICATION SYSTEMS (UNICS)

Description
The goal of this project is to explore different alternatives for opportunistic spectrum usage policies and techniques for future wireless networks and to develop sufficient theoretical tools for analyzing them. One fundament question in the analysis is related to the modeling principles of e.g. radio channel models, mobility models and traffic models for flexible heterogeneous wireless networks. The project has three closely related themes: 1) spectrum sensing methodology for cognitive radios, 2) radio resource management in flexible wireless networks, and 3) channel and traffic modeling for broadband heterogeneous wireless networks.

The principal investigator of the project is Professor Matti Latva-aho.

Requirements
Good knowledge on wireless communications, elements of information theory and mathematical optimization, knowledge of wireless networking and resource management are required.

To successfully occupy the position of a Doctoral Student, the applicant must possess an applicable Master of Science degree or an equivalent degree from a foreign institution of higher education.
