    Stratégies d’adaptation des communautés rurales à la précarité hydrique dans la commune urbaine de Téra, dans le Liptako Nigérien by Yayé Moussa

    Published 2022-04-01
    “…They are thus implementing a variety of strategies (diversification of water supply sources, massive recourse to traditional water points, mixed uses, pooling of water points, et cetera) arranged in a seasonal chronology that allows for the creation of complementarity between villages with different water situations, on the one hand, and on the other hand, between the insufficient number of modern water points and the traditional points that are still at the centre of the rural communities' water supply system. However, with the explosion of needs (population and livestock growth), in a context of global warming, the water problem is likely to deteriorate further because of the pressure on the resource and call into question the social responses contributing to universal access to water. …”

    New multiple access and waveform technology for 6G by Hua LI, Shiya HAO, Caihong GONG, Qianqian LI, Xiaoming DAI

    Published 2022-10-01
    “…With the explosive growth of Internet devices, the 5G new radio (NR) system faces congestion and high latency issues due to the low access efficiency of traditional orthogonal multiple access (OMA).Besides this, the performance of the orthogonal frequency-division multiplexing (OFDM)-based system is severely degraded due to the Doppler effect in high-speed scenarios.To meet the low-latency, high-reliability, and massive connection requirements of 6G communication in high-mobility scenarios, firstly, a novel orthogonal time frequency space (OTFS)-based pattern division multiple access (PDMA) scheme, shortened as OTFS-PDMA, was proposed.Then, the system input-output relationship of different types of PDMA codeword allocation schemes in the delay-Doppler (DD) domain was derived.Finally, a low-complexity expectation propagation algorithm (EPA)-based receiver was proposed.Simulation results illustrate that the proposed OTFS-PDMA scheme achieves significant performance gains over the conventional OTFS-OMA scheme.For regular PDMA patterns, the PDMA codeword allocation has a slight impact on the system performance.For irregular patterns, the centralized spreading method outperforms the discrete one.For discrete spreading scheme, the system can achieve better performance by assigning irregular PDMA spread signals along the Doppler direction.In addition, the proposed EPA receiver outperforms its conventional counterparts.…”

    DropBlock based bimodal hybrid neural network for wireless communication modulation recognition by Yan GAO, Jian SHI, Shengyu MA, Bolin MA, Guangxue YUE

    Published 2022-05-01
    “…As an intermediate step of signal detection and demodulation, automatic modulation recognition played a momentous role in wireless communication system.Aiming at the low recognition accuracy of existing automatic modulation recognition methods, a bimodal hybrid neural network (BHNN) was proposed, which utilized complementary gain information contained in multiple modes to enrich feature dimensions.The improved residual network was connected in parallel with the bidirectional gated loop unit to construct a bimodal hybrid neural network model, and the spatial and temporal features of the signal were extracted respectively.The DropBlock regularization algorithm was introduced to effectively suppress the influence of over fitting, gradient disappearance and gradient explosion on the recognition accuracy in the process of network training.Using bimodal data input, the spatial and temporal characteristics of signals were fully utilized, and the network depth was reduced through parallel connection.The model convergence was accelerated, and the recognition accuracy of modulated signals was improved.In order to verify the effectiveness of the model, two public datasets were used to simulate the model.The results show that BHNN has high recognition accuracy and strong stability on the two datasets, and the recognition accuracy can reach 89% and 93.63% respectively under high signal-to-noise ratio.…”
