A wireless sensor network designates a system composed of numerous sensor nodes distributed over an area in order to collect information. The sensor nodes communicate wirelessly with each other in order to self-organize into a multi-hop network, collaborat ...
Location finding for CDMA subscribers using an antenna array at the base station and deploying multiple base stations is studied in this paper. Two methods are considered for radio location: measured time-of-arrival (TOA) and angle-of-arrival (AOA), and al ...
Pilot-assisted channel estimation for communication systems employing orthogonal frequency division multiplexing modulation requires significant signal processing at the receiver if the correlation among the frequency-domain channel coefficients is to be e ...

In the present study, we are interested in verifying how the progressive addition of constraints on communication and localization impact the performance of a swarm of small robots in shape formation tasks. Identified to be of importance in a swarm-user in ...
The invention concerns a device for automatically and rapidly locating (10) a person or an object at sea in poor meteorological conditions, comprising a radio wave transmitting device (20) provided on the person or the object and a reception device (30), p ...
In this thesis, we focus on Impulse Radio (IR) Ultra-WideBand (UWB) ranging and positioning techniques under indoor propagation environments. IR-UWB, a new carrierless communication scheme using impulses, is a candidate technology for future communication, ...
Emerging pervasive wireless networks, pocket switched networks, Internet of things, vehicular networks and even sensor networks present very challenging communication circumstances. They might involve up to several hundreds of wireless devices with mobilit ...
Location finding for CDMA subscribers using an antenna array at the base station is studied. Two methods are considered for radio location that are based on time of arrival (TOA) and angle of arrival (AOA) measurements. For TOA estimates, a maximum likelih ...
The present invention concerns a receiver and a method for retrieving data from Ultra wideband radio transmission signals received by a receiver and transmitted in packets containing at least a preamble known to the receiver and a payload containing data u ...
