Title: Quantifying and Extracting Visual Information from Mobile Devices
Due to advancement in minimization and mass-production, cameras are ubiquitously embedded in most of current mobile devices including phones, vehicles, robots, and augmented-reality displays. These mobile cameras are cheap and can gather in real-time large amounts of streaming data about the surrounding environment. Using an information-theoretic model of a streaming video captured by a mobile camera, we precisely characterize the information rates of this captured data. These results support a holistic approach that combines geometric reconstruction with semantic recognition for visual perception of dynamic environment. We then highlight several work in our group following this approach for extracting visual information from mobile devices including camera pose estimation, 3D environment mapping, and object localization and recognition.

Title: Wireless-Powered Communication Networks: Architectures, Protocols, and Applications
This talk will provide a comprehensive review on the state-of-the-art research and technological developments on the architectures, protocols, and applications of the wirelesspowered communication networks. The talk will start with an introduction to the circuit design of wireless-powered communication devices. Then the talk will discuss about the architecture and protocol design issues for the wireless-powered communication networks. Different wireless network architectures including single-hop networks, multihop relay networks, centralized and decentralized networks, and multi-antenna systems for RF energy harvesting and wireless energy transfer will be covered. Then the talk will delve into different physical, radio link/MAC, and network layer protocol design issues to support and utilize wireless energy harvesting and transfer capability. Next the talk will discuss about applications of energy harvesting and transfer in different wireless networking scenarios, for example, those in cellular networks, sensor networks, cognitive radio networks, mobile ad hoc and delay tolerant networks. In addition to reviewing the existing approaches for architecture, protocol, and application design in wireless powered communication networks, the talk will outline some emerging research directions in this area.

Prof. Hikmet Sari, France
Title: Power Efficiency in Wireless Communications – A Historical Review
In this talk, we focus on power efficiency and give a historical review of some major advances in transmission and multiple access, which shaped the development of the wireless communications standards developed over the past two decades. The review includes the development of OFDM and single-carrier transmission with frequency-domain equalization (SC-FDE) as well as the birth of OFDMA and of single-carrier FDMA (SC-FDMA), which were adopted by the Mobile WiMAX and the 3GPP LTE standards. Next, we address the nonlinear distortion problems caused by the high-power amplifier (HPA) at the transmitter in wireless communications systems and describe the various techniques devised to compensate for this phenomenon in single-carrier and multicarrier transmission. We emphasize the fact that the optimum operating point of the power amplifier cannot be always achieved in practice due to the stringent spectral masks imposed. We describe ideal signal predistortion that is applicable to both single-carrier and multicarrier systems and then we discuss peak-to-average power ratio (PAPR) reduction for multicarrier systems. We point out the fact that the gain achieved in terms of PAPR does not directly translate in terms of transmitted signal power for a given power amplifier. The issues highlighted in this talk are of significant interest to current 4G as well as future 5G systems.
