My Expertise
Energy efficiency, high data rates, and security are the main driving forces for the evolution of wireless communication networks. Traditionally, these requirements have been fulfilled by increasing both the transmit power and the bandwidth. However, nowadays the radio spectrum available for wireless services is extremely scarce and universal frequency reuse is a new trend to accommodate the increasing number of users. In other words, increasing the transmission bandwidth will not always be an option in the future. On the other hand, power consumption in cellular networks is not only a financial burden to service providers, but also a main contributor to greenhouse gas emission. Besides, due to the universal frequency reuse, strong co-channel interference puts system designers in a dilemma since increasing the transmit power may not be beneficial for the overall system performance. As a consequence, a better system design for utilizing the limited resources is needed. My research interest is the design of resource allocation algorithms for realizing spectral efficient, energy efficient, and secure communication networks.
