%X Recently, Millimeter Wave (mmWave) systems have emerged as a potential solution for the spectrum secrecy problem suffered by current wireless technologies. However, practically implementing such systems is challenging as they suffer from high hardware complexity and power consumption. Therefore, analog beamforming is considered the most suitable approach for practical implementation of such systems, relaxing the hardware and power consumption requirements compared to full digital beamforming solution. Moreover, hybrid beamforming solutions emerged as an attractive solution that can capture the trade-off between digital and analog ones. In this paper we show mathematically that in pure Line of Sight (LoS) channels, using hybrid beamforming with Zero Forcing (ZF) at the baseband can achieve equivalent Spectral Efficiency (SE) compared to the full digital ZF precoding, with lower hardware complexity, and lower power consumption. Moreover, we validate the equivalence in SE performance between hybrid ZF and digital ZF by simulation results.

%X In this paper, for the first time, we propose two new solutions to boost the data rate between small connected objects such as glasses and cams and the 5th generation (5G) mobile network, based on spatial modulation, single-carrier waveform, compact reconfigurable antennas at the object side and massive multiple input multiple output (M-MIMO) at the network side. In the first new wireless communication system, a "transmitting object" uses transmit spatial modulation with a compact reconfigurable antenna and a constant envelop amplifier to transmit in high data rate with low complexity and low power consumption. The space-time digital processing capability of the M-MIMO 5G base station is used to detect such signal. In the second new wireless communication system, a "receiving object" uses receive spatial modulation, a compact multiport antenna and a low complexity detection algorithm to receive in high data rate with a low complexity signal processing. The space-time beamforming capability of the M-MIMO 5G base stations is exploited to deliver a signal that is pre-equalized enough to be detected by the object. For the first time, we present experiments showing that M-MIMO allows for the re-introduction of single-carrier modulation waveform. For the first time, we present performance results obtained with real existing compact antennas and compact reconfigurable antennas, showing that the two new communication systems outperform conventional modulation in terms of energy efficiency and complexity.

%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 spectrum deadlock suffered by the current wireless networks. However, operating at such high frequencies is obstructed by many issues. Two of the main 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 paper we 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 algorithm achieves higher performance in terms of SE and robustness to blockage compared to the existing techniques in the literature.

%X Geolocation of high frequency (HF) transmitters at distances in the order of 2000 km is possible by exploiting the time difference of arrival (TDoA) among multiple distributed single antenna receivers. HF radio signals propagate via skywaves between the Earth‐Ionosphere medium and the signals are received through non‐line‐of‐sight mode. This experimental study demonstrates that it is possible to evaluate the TDoA between two receivers for a HF radio broadcast signal propagating through the ionospheric channel. The HF propagation path geometry for one hop propagation mode is explained. Simulations are performed using this model to evaluate the theoretical TDoA between the signals received at two synchronized receivers. In the second step, two remotely controllable receivers built to capture distinct HF signals are deployed in two cities in France. Radio broadcast signals from different HF transmitters across Europe are captured simultaneously on the two synchronized receivers. The TDoA is obtained by cross‐correlating the captured signals from the receivers. The TDoA obtained by experimental and simulation methods are compared for different radio propagation paths and results show some very good agreement.

%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 This paper presents the geolocation of a High Frequency (HF) transmitter (Tx) located at distances of about 700 to 1300 km from a network of receivers (Rx's). HF signals propagate through the ionospheric medium using skywaves and are reflected back to the Earth, thereby allowing HF communications over long distances. In our study, the location of the HF Tx is found using time difference of arrival (TDoA) method. Four remotely controllable Rx's which are built to capture HF signals synchronously are installed in four different cities in France. HF radio broadcast signals are captured simultaneously on the four deployed Rx's from the HF Tx situated in Nauen, Germany. The TDoA's between the signals received on all the four synchronized Rx's are obtained using the cross-channel sounding method. Using the obtained TDoA's, the Tx location is found using the geolocation algorithm based on TDoA. Experimental results show that it is possible to locate the HF Tx in Nauen with a geolocation error of about 5 km.

%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.
