Although rare, masses and mass-like lesions of developmental and genetic origin may affect the paediatric craniofacial skeleton. They represent a major challenge in clinical practice because they can lead to functional impairment, facial deformation and disfigurement. The most common lesions include fibrous dysplasia, dermoid cysts, vascular malformations and plexiform neurofibromas. Less common lesions...
The high demand of low-power radio transceivers for the Internet of Things drives the design of innovative wireless architectures. In this context, the energy efficiency problem arises from the strong variability of the radio channel. As a solution, we propose to dynamically optimize the receiver performance jointly with the power consumption, in order to reach a low-margin operating mode. For this...
The emerging market of the Internet of Things is constrained by the energy-efficiency of each layers having a role in Wireless Personal Area Networks (WPANs). In this context, adaptivity is a key technique to address the need of low-power consumption in unpredictable environments, by providing at any time a low-margin operating mode. For this purpose, the paper presents an IEEE 802.15.4 digital baseband...
Energy-efficient wireless communications are key enablers for the development of smart objects. New architectures with very low-power profile have to be investigated for targeting advanced implementations. In this context, the paper proposes to employ the Compressive Sensing theory for the detection of M-ary orthogonal signals, without complete recovery. This allows to lower the digital baseband computation...
With the expansion of Internet of Things (IoT) the design of highly-integrated radio transceivers is a challenging task. The major concern is the power consumption, which is generally non-optimal due to the fluctuation of the communication channel quality. In this paper, we propose the use of downsampling techniques for decreasing the computational load of the baseband signal processing. More precisely,...
