In this paper, we derive a signal processing algorithm that enables a Wi-Fi station to passively detect the presence of a potential user in its vicinity. It is assumed that the potential user either doesn’t carry a Wi-Fi device or, if it does, that

The use of millimeter wave technologies offer a promising solution for dense small cell networks, despite having to contend with challenging propagation characteristics. In particular, user-induced effects can lead to significant channel variations d

We explore the symmetric degrees of freedom (DoF) of partially connected interference networks for the case in which transmitters have no knowledge of their channel states (channel coefficients and coherence times) but are aware of the network topolo

Ultra broadband mobile communication is a key requirement of fifth generation (5G) wireless cellular networks. To fulfill this requirement much larger bandwidth is needed which can be delivered in millimeter band from 30 to 300 GHz. Beam formed trans

Receiver algorithms which combine belief propagation (BP) with the mean field (MF) approximation are well-suited for inference of both continuous and discrete random variables. In wireless scenarios involving detection of multiple signals, the standa

This paper presents a new asynchronous modulation classifier for digital amplitude-phase modulated signals in flat-fading channels when the channel state is assumed unknown. In the design of this classifier, we propose new estimators for the unknown
