Research Interests
Prof. Cimini's research interests focus on wireless communications, in particular the use of multiple antennas and multiple carriers to enhance the performance of multiuser wireless applications. In addition, he is also studying the application of MIMO techniques to enhance the resolution of future radar systems.
The many innovations in wireless systems over the past ten years, such as OFDM, MIMO, and multiuser detection, have led to tremendous gains in performance, and even more significant gains are promised. For most of these techniques, the maximum benefit is achieved only when knowledge about the environment is complete and correct. Depending on the application scenario, the required information might include the characteristics of the radio channel, including interference, the structure of the network, or the global connection tables used for routing. In many practical situations, however, the required information is either not available or not reliable. In our work, we focus on evaluating the effects of incomplete information on performance and develop algorithms which work well in the presence of these uncertainties. Both ad hoc and statistically robust algorithms have been developed and quantified. Current work focuses on the MAC and network layers of the protocol stack, especially on adaptive resource allocation, OFDMA, cooperative and opportunistic networks, and physical-layer-based routing.
