Wireless Channel Modelling Multipath Environment

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.
