A new algorithm is proposed to efficiently find an optimal base station configuration for indoor CDMA networks from a set of potential base station sites. It considers both forward link and reverse link signal-to-interference ratio (SIR) constraints. The proposed algorithm is a combination of a heurisitc algorithm and selective brute force search. The heurisitc algorithm estimates the minimum number...
We provide the first rigorous analytical results for the connectivity of dynamic random geometric graphs - a model for mobile wireless networks in which vertices move in random directions in the unit torus. The model presented here follows the one described. We provide precise asymptotic results for the expected length of the connectivity and disconnectivity periods of the network. We believe that...
This paper addresses adaptive channel estimation for time-varying mobile wireless channels with nonstationary statistics. We presents a reduced complexity adaptive channel estimator based on a set membership filtering approach known as the Optimal Bounding Ellipsoid (OBE) algorithm. To exploit time and frequency domain correlation properties of the channel in an efficient low-complexity way, we allow...
