…with a conversion efficiency bandwidth covering 90% of 43.47 %, starting from 1.8 GHz to 2.8 GHz. This indicates the polarizer’s wideband CP performance, with a pure CP centered at…
…the convergence between low-pow-er wide area network (LPWAN) grade massive machine-type communication (mMTC) wireless technologies and satellite (especially low Earth orbit, LEO) systems. In the article, we discuss the alternative…
…of 6G, and real-life scenarios towards 2030. ”6G networks are expected to be in commercial use around 2030. It is time to start building a comprehensive vision of 6G verticals…
In this paper a novel framework is proposed to optimize the downlink multi-user communication of a millimeter wave base station which is assisted by a reconfigurable intelligent reflector (IR). In…
Sustainability has entered all aspects of life, calling for an active approach from the wireless and mobile communications community to help in solving fundamental challenges facing societies. Societal, economic, and…
In this paper a novel framework is proposed to perform data-driven air-to-ground channel estimation for millimeter wave (mmWave) communications in an unmanned aerial vehicle (UAV) wireless network. First an effective…
In this paper, a novel framework for guaranteeing ultra-reliable millimeter wave (mmW) communications using multiple artificial intelligence (AI)-enabled reconfigurable intelligent surfaces (RISs) is proposed. The use of multiple AI-powered RISs…
In this paper, a compact textile ultrawideband (UWB) planar monopole antenna loaded with a metamaterial unit cell array (MTMUCA) structure with epsilon-negative (ENG) and near-zero refractive index (NZRI) properties is…
…underlined sentence-to-sentence similarity are examined and scrutinized. Next, to overcome inherent limitations of WordNet semantic similarity in terms of accounting for various Part-of-Speech word categories, a WordNet “All word-To-Noun conversion”…
…to the presence of phase errors arising from limited quantization levels as well as hardware impairments at the RIS elements is also discussed. First, the composite channel containing the direct…
