%X Millimeter-Wave (mmWave) channels are characterized as being sparse and Line of Sight (LoS) dominated. Applying hybrid beamforming in mmWave systems guarantees Multi-User (MU) transmission with low hardware requirements. Zero Forcing (ZF) precoding can be utilized at the digital layer of the hybrid beamformer to mitigate the Inter User Interference (IUI). However, due to the sparse nature of the mmWave channels, a ZF precoder may provide limited performance due to the highly correlated MU channel matrix. The aim of this paper is hence to address the interference mitigation problem in the analog domain before handling it at the ZF digital level. Signal to Leakage and Noise Ration (SLNR) based users selection algorithm is introduced for maximizing the Spectral Efficiency (SE) of the system with low complexity requirements.We finally highlight by simulations the potential gains achieved by the introduced interference aware users selection approach.

%X Millimeter-Wave (mmWave) systems are considered as one promising potential to solve the scarce spectrumdeadlock suffered by the current wireless networks. However, operating at such high frequencies is obstructed bymany issues. Two of themain key challenges are the hardware complexity limiting the implementation of fully digital beamforming system, and the frequent propagation ray blockage due to the small wavelength. Recently a lot of research has thus been dedicated to hybrid beamforming solutions to adapt with hardware limitations, but also trying to solve the ray blockage problem. In this paperwe introduce a novel hybrid beamforming framework that captures the diversity of the multipath sparse channel in the analog domain using the Equal Gain Transmission (EGT) spatial precoding scheme. We first highlight how such beamformer can enhance both the Spectral Efficiency (SE) and the robustness of the communication system. Then, we unleash the potentials of the Digital Signal Processing (DSP) layer to suppress the Multi-User (MU) interference using the Zero Forcing (ZF) approach. We introduce a generic and realistic channel blockage model to evaluate the robustness of our solution. We show through simulations that our algorithmachieves higher performance in terms of SE and robustness to blockage compared to the existing techniques in the literature.

%X In the context of passive geolocation of High Frequency (HF) transmitters using the Time Difference of Arrival (TDoA) method, the transmitted signal and the propagation channel is unknown. This paper explains the principle of a method termed as "cross-channel sounding" along with its concepts. This method is used to evaluate the propagation duration differences of an unknown signal received by multiple synchronized distributed receivers. The mathematical description for cross-channel sounding is detailed, emphasizing the importance of the nature of the transmitted signal in the estimation of the propagation duration differences. An operational country wide TDoA receiver network capable of capturing HF signals is presented. HF broadcast signals are captured from different transmitters around Europe. Experimental data are used to analyze the different propagation modes from cross-channel sounding and assess the TDoA estimation complexity in the case of multipath channels.

%X Determining the geographic location of high frequency (HF) transmitters is of prime importance in both defense and civil operations. In this letter, we present experimental results of distant HF transmitter geolocation performed using the time difference of arrival (TDoA) method. The HF signals considered for our study are transmitted from different locations across Europe. Multiple receivers capable of capturing HF radio signals synchronously are built and a nationwide receiver network with centralized control is deployed in France to assess the feasibility of our approach. HF radio signals are captured simultaneously by all receivers in the network from different European HF broadcast transmitters. From the captured data, the propagation duration differences between the signals received by all receivers are obtained using the cross-channel sounding method. Finally, the transmitter location is estimated using the geolocation algorithm based on the TDoA method. Experimental results demonstrate that it is possible to locate the HF transmitters under favorable conditions with a relative geolocation error ranging from about 0.1 to 10% of the actual ground distance, for most of the experimental scenarios.

%X Millimeter-Wave (mmWave) systems recently attracted attention as one of the key enablers for the Fifth Generation (5G) networks. The small wavelength at mmWave frequencies enables deploying massive Multiple Input Multiple Output (MIMO) antenna arrays at the transmitter and receiver sides with reasonable form factor. However, massive MIMO mmWave systems suffer from a lot of practical limitations, specifically due to channel and hardware characteristics at such high frequencies. In this poster we propose multiple solutions to design a realistic massive MIMO cellular system that takes into account the imposed limitations and achieves considerable gains in terms of spectral efficiency.

%X In this paper, we present a new and intuitive way to show important green techniques for the future fifth generation of mobile networks such as adaptive beamforming to the general public. We use a new device called the Radio Waves Display, which is a one meter square panel composed of twenty by twenty radio frequency sensors spaced by five cm. The Electromagnetic Field strength measured by each sensor is converted into visible light. This new device enables a direct visualization of the waves that pass through it, in real time. It enables us to show to the general public, which is naturally more concerned about the energy consumption of devices, that the network energy efficiency as well can be improved. Most of the presented demonstrations have been effectively shown to a general public at the Mobile World Congress 2016 and other events.

%X Cet article présente un prototype de récepteur capable d'enregistrer, à distance, des signaux haute fréquence (HF). Le composant de base de ce récepteur est un équipement de radio logicielle, ou Software Defined Radio (SDR), qui peut être configuré pour enregistrer des données selon la nécessité de l'utilisateur. Les échantillons radio enregistrés à partir d'un réseau d'au moins quatre récepteurs non co-localisés permettent la localisation de l'émetteur en utilisant la méthode "Time Difference of Arrival" (TDoA). Tous les récepteurs sont synchronisés avec une même référence temporelle pour obtenir la meilleure précision de géolocalisation. Les signaux radio enregistrés peuvent également être utilisés pour l'analyse et la modélisation du canal de propagation HF, ainsi que la caractérisation du milieu ionosphérique.

%X La caractérisation expérimentale et la modélisation des cibles sont essentielles dans l'optimisation des systèmes de détection tels que les radars automobiles d'aide à la conduite. Dans la bande W (75-110 GHz), la dimension des objets rend difficile leur prise en compte en simulation et la description par une seule valeur de SER n'est pas toujours suffisante. Nous proposons une méthode expérimentale, inspirée de la technique SAR, associée à une modélisation pour la description des objets à l'aide de points brillants ainsi qu'un algorithme simple de construction d'image.

%X Ce papier décrit une méthode de caractérisation en bande W de cibles radar électriquement larges. Les signatures électromagnétiques de différents véhicules ont été mesurées dans une grande salle de gymnase. La configuration de mesure proposée a pour but l'extraction de points brillants pour la modélisation de la cible. Ainsi, lors de la simulation de scénarios routiers pour des applications radar automobile, leur utilisation pour représenter les cibles permettra de réduire considérablement le temps de calcul.
