Research


Research in the ViVoNets Lab is concerned with all aspects of the transmission of voice, audio, still images, and video over mulithop, wireless, heterogeneous networks, with a particular emphasis on handheld devices and highly mobile broadband networks. On-going research in the Lab includes the design of lossy compression methods for narrowband and wideband voice, multichannel audio, and high dynamic range and 3-D video, the development of new functionalities for existing compression methods, joint source/channel coding, packet loss concealment and robust encoder design, PHY/MAC/Application cross layer designs, adaptive modulation and coding, source and channel diversity methods, and end-to-end performance optimization for the human user. We are also interested in preprocessing and postprocessing methods, such as video stabilization, scene relighting, and color equalization, particularly for multiple cameras. The overarching goals of the work are to advance the understanding of fundamental limits on system performance and to contribute to the state-of-the-art in digital signal processing, perceptually based performance measures, source coding, channel coding, and modulation.
