This paper addresses the problem of data detection in orthogonal frequency division multiplexing (OFDM) systems operating under a time-varying multipath fading channel. Optimal det...
A new notion of security boundary is introduced to model multilevel security policies in the scenario of mobile systems, within Cardelli and Gordon's "pure" mobile ...
Location models are crucial to location-aware applications. In this paper we present two approaches for modeling location information in an infrastructure-based and an ad hoc netwo...
Threshold signature schemes are examples of threshold cryptosystems, as introduced by Desmedt, [4]. The purpose of this paper is to present a rather simple alternative to threshol...
We consider transmission using transmit and reception using receive antennas in a wireless environment assuming that neither the transmitter nor the receiver knows the channel coef...
