As the demand for wireless mobile communication services is constantly growing, the need for mobile systems and devices that support much higher data rates is increasing. The available bandwidth is limited and expensive, thus we need new technologies that ...
Naouel Ben Salem, Levente Buttyan, Jean-Pierre Hubaux and Markus Jakobsson abstract: In multi-hop cellular networks, the existence of a communication link between the mobile station and the base station is not required: a mobile station that has no direct ...
In multi-hop cellular networks, data packets have to be relayed hop by hop from a given mobile station to a base station and vice-versa. This means that the mobile stations must accept to forward information for the benefit of other stations. In this paper ...
With the convergence of internet and wireless communications, a plethora of new services will originate. A natural application for cellular radio networks is that of radiolocation, in which the mobile unit can be positioned based on the signals received at ...
The spectrum of deployed wireless cellular communication systems is found to be under-utilized, even though licensed spectrum is at a premium. In this paper, we design a system with an ad hoc overlay network, which we denote as the secondary system (SEC), ...
We address the problem of a non-supervised bidimensional segmentation method based upon a discrete-level unilateral Markov field model for the labels and conditionaly Gaussian densities for the observed voxels. Such models have been shown to yield numerica ...
Location finding searchers have recently emerged as essential elements in future CDMA wireless systems. In this paper we present a new combined architecture for location searchers and conventional RAKE receivers, which is based on multiplexing common hardw ...
The spectrum of deployed wireless cellular communication systems is found to be under-utilized, even though licensed spectrum is at a premium. To efficiently utilize the bandwidth left unused in a cellular system, which we denote as the primary system (PRI ...
Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...
This paper provides an asymptotic performance evaluation of network based or multilateral radio location estimators that use the time of arrival (TOA) and/or the angle of arrival (AOA) measurements of the signals travelling from a mobile station (MS) to a ...
