Today’s mobile technology features several sensors that when integrated can provide ubiquitous navigation assistance to pedestrians including wheelchair users. Common sensors found in most smartphones are Global Positioning System (GPS), accelerometer, and compass. In this paper, a user’s movement pattern recognition algorithm to improve map matching efficiency and accuracy in pedestrian/wheelc...

In this communication, a substrate integrated waveguide (SIW) end-fire antenna array with zero clearance is proposed for fifth-generation (5G) mobile applications using machine learning-assisted optimization. particular, novel impedance matching architecture that involves three arbitrary pad-loading metallic vias investigated and adopted the element. Due to stringent design requirements, locati...
