A China-led team of researchers has developed a powerful brain implant electrode array that is as soft as brain tissue, thinner than a strand of hair and more durable than anything before it. In ...

Abstract: Recently, the design of omnidirectional precoding has been widely studied for massive multiple-input multiple-output (MIMO) systems. For the base station (BS) equipped with a uniform ...

Ever since humans began building, they’ve been building up. Throughout the millennia, our constructions have reached higher and higher into the sky, spurred by various motivations: religion, democracy ...

Abstract: This paper presents a dual-band split-ring structure that provides end-fire radiation characteristics for multi-input multi-output (MIMO) mm-wave 5G applications. The proposed single antenna ...
