Summary
Abstract
The consistency and performance of wireless receivers depend on the quality of the signal received. In urban canyons, wireless signals are affected by the surrounding objects, such as high buildings, trees, and so on, which introduce multipath errors. Multipath arises from the reception of reflected or diffracted signals, possibly in addition to the line-of-sight signal, and is one of the most detrimental error sources in GNSS positioning. Since obstacles are always present in practical applications, several statistical representations have been developed over the years to measure, predict, and compensate for errors induced by obstructions. This talk will cover some existing channel models for wireless LOS and NLOS scenarios.
Speaker
Dr Nitin Sharma received his PhD degree from the Birla Institute of Technology and Science (BITS), Pilani, India, in 2014. His research dissertation is on wireless communication. He is currently an Associate Professor with the Department of Electrical and Electronics Engineering (EEE), BITS Pilani, K K Birla Goa Campus, Pilani, India. His current research interests include optimization in wireless communication, resource allocation and management for wireless and wired communications, machine to machine (M2M)/Internet-of-Things (IoT) communications, cloud communications, and evolutionary computations. He is also working in the area of global navigation satellite system (GNSS) signal processing.
