AoA Estimation of Spatially Correlated MIMO Transmitters in Wireless Passive Radar Applications
Argyriou A. (2022)In this work we are concerned with the problem of estimating the AoA of MIMO transmitters when their antennas exhibit spatial correlation. The problem is of interest in passive RADAR applications where a receiver that is ... -
Cache-assisted interference cancellation in the multi-user downlink fading channel and its application in HetNets
Argyriou A. (2019)Next generation wireless systems will be characterized by two things among others: the dense deployment of small cell base stations (SBS), and caching of popular data files at the edge. In this paper we study the downlink ... -
Data collection from resource-limited wireless sensors for cloud-based applications
Argyriou A. (2015)We consider a wireless sensor network (WSN) where each sensor node samples a random signal, places the digitized data in a buffer, and transmits the data to an access point (AP) through a wireless packet erasure communication ... -
Forwarding interfering signals in wireless ad hoc networks under MRC receiver processing
Argyriou A. (2015)Cooperation in wireless networks is embraced today both from cellular and device-to-device (D2D) communication standards. The reason is that this communication paradigm offers much-needed improvements in the spectral ... -
Interference decoding in cellular wireless relay networks with space-time coding
Argyriou A. (2016)In this paper we propose a cooperative protocol and a symbol decoding algorithm that target improved performance in the presence of inter-cell interference (ICI) in wireless cellular networks. Our scheme uses the wireless ... -
Joint Estimation of the Number of Antennas and AoA of a Wireless Communication Transmitter
Argyriou A. (2022)Estimating various parameters of a wirelessly transmitted information-bearing signal, besides the information itself, is essential for a number of applications (e.g. military finger-printing, localization, radio-astronomy, ... -
Multi-Source Cooperative Communication with Opportunistic Interference Cancelling Relays
Argyriou A. (2015)In this paper, we present a multi-user cooperative protocol for wireless networks. Two sources transmit simultaneously their information blocks and relays employ opportunistically successive interference cancellation (SIC) ... -
Number of Sources Detection and AoA Estimation of a Wireless Transmitter in Multipath Channels
Argyriou A. (2022)Detecting the number of sources from which the signal of a single wireless transmitter has originated, as well as estimating its angle-of-arrival (AoA), are critical parameters for a plethora of remote sensing applications ... -
Passive Angle-Doppler Profile Estimation for Narrowband Digitally Modulated Wireless Signals
Argyriou A. (2022)In this paper, we improve estimation of the Doppler shift present in signals that originate from multiple wireless digital communication transmitters. We deploy a uniform linear array (ULA) that overhears the frequency ... -
Power-efficient estimation in IEEE 802.11ah wireless sensor networks with a cooperative relay
Argyriou A. (2015)We consider a wireless sensor network (WSN) where each sensor node samples a random signal and transmits the result to an access point (AP)/fusion center (FC). The WSN operates under the sub-1GHz IEEE 802.11ah MAC/PHY ... -
Secrecy in wireless communication through closed-loop receiver de-synchronization
Argyriou A. (2020)A subset of the synchronization algorithms in a wireless receiver are responsible for tracking the phase and frequency of a digitally modulated signal. If variations of the phase in the signal are substantial, then the ... -
User cooperation in heterogeneous cellular networks for improved spectral efficiency
Argyriou A. (2015)In this paper we propose user cooperation in Heterogenous cellular networks (HCNs) for combating intra-cell interference and improving downlink spectral efficiency (SE). The main idea we put forward is to employ interference ...
