We present a linear multicast of an analog signal in a two-pump self-seeded parametric device. The linearity of the parametric multicasting is assessed by two-tone measurements of the third-order intermodulation products and radio-frequency spectral analys ...

This paper presents a new radio architecture targeting RF transceivers for WSN, WBAN, and biomedical applications. The high miniaturization required by such applications is achieved thanks to the combination of high-Q MEMS devices, such as RF BAW re ...
In mobile and wireless networks, data broadcasting for popular data items enables the efficient utilization of the limited wireless bandwidth. However, efficient data scheduling schemes are needed to fully exploit the benefits of data broadcasting. This mo ...
Sensor localization from only connectivity information is a highly challenging problem. To this end, our result for the first time establishes an analytic bound on the performance of the popular MDS-MAP algorithm based on multidimensional scaling. For a ne ...
This paper addresses the problem of determining the node locations in ad-hoc sensor networks when only connectivity information is available. In previous work, we showed that the localization algorithm MDS-MAP proposed by Y. Shang \textit{et al} is able to ...
A fundamental problem in wireless networks is determining the broadcast capacity, i.e., the maximum data transfer rate from a given node to every other node in a relay network. This paper studies the scaling of the broadcast capacity for a network with a s ...
In this work we consider the problem of sensor localization when only the connectivity information is available. More specifically, we compare the performance of the centralized algorithm MDS-MAP with its distributed version HOP-TERRAIN. We show that both ...
Spectrum sensing is one of the enabling functionalities for cognitive radio (CR) systems to operate in the spectrum white space. To protect the primary incumbent users from interference, the CR is required to detect incumbent signals at very low signal-to- ...
The invention relates to a method and a device for wireless transmission between at least one first transducer (T1) arranged in a first location and at least one second transducer (T2) arranged in a second location remote from the first location without us ...
Formal research on Ultra-wideband (UWB) technology started in the U.S. in 2002; where its definition was formulated and the frequency allocation in that country established. However, the first ultra-wideband transmission was done during the confirmation of ...
