In recent years, wireless data traffic has exponentially grown due to a change in the way today’s society creates, shares and consumes information. This change has been accompanied by an increasing demand for higher speed wireless communication. Massive MIMO links are expected to become a reality within the next ten years. Towards this aim, the Massive MIMO communication is envisioned as one of the key wireless technologies of the next decade. These very high bit-rates will enable a plethora of long-awaited applications, such as ultra-fast massive data transfers among nearby devices, or high-definition videoconferencing among mobile personal devices in small cells, also to address spectrum scarcity and capacity limitations of current cellular systems. The latter application of current cellular systems is one of the most critical one that motivates one to carry out research in this particular area. Nevertheless, due to the difficulties in implementing Massive MIMO technology able to operate at ultra-high speeds, the limited efficiency of individual components (specifically antennas), and the very-high and frequency-selective path-loss of the MIMO channel, there are several research challenges both from the device and the communication perspectives that require innovative solutions and the revision of well-established concepts in wireless communications. This proposal deals with the wireless communications perspective of the design of these algorithms, which could enable the Massive MIMOs to be incorporated in the current cellular systems and enable a huge data rate era to be envisioned.
We, in this project, aim to look upon some of these research challenges from a theoretical perspective and our goal is to build efficient algorithms for this technology, which is said to be the next breakthrough in wireless communications. This would not just help the international community to gain insights into these solutions, but the local community would also get benefits to keep pace with the global walk. We intend to hire highly motivated graduate students in this project who will work on various aspects of the algorithms from protocol design to mathematical modeling to numerical simulations to results. The key contributions of this project will be 1) to design novel transmitter and receiver design algorithms for Massive MIMO systems and 2) to establish mathematical foundations and theoretical analysis on various signal processing tasks that are inevitable for this technology to come into being. Extensive simulations test-beds will be created to help understanding the major issues and potential solutions of this regime. A highly motivated and learned human resource would be produced with eminent degrees in engineering by virtue of this research.
