LTE Cellular Receiver Design and Signal Processing for Urban Navigation

Abstract

Position and navigation have become increasingly indispensable in a variety of applications, e.g., unmanned aerial vehicles, intelligent transportation, and social networking. Nevertheless, the position solution solely relying on global navigation satellite system (GNSS) receivers in urban canyons may be inaccurate or even not available. Cellular long-term evolution (LTE) signals are potential signals-of-opportunity for position and navigation. However, accurate and reliable tracking of LTE signals under highly dynamic urban channel conditions remains a challenging task.

This talk will present the LTE software-defined radio receiver design for urban navigation. The distinct structure of the LTE signal compared to those of the GNSS signals will be discussed. LTE signal processing algorithms with adaptive multipath mitigation will be explained. Both simulation and experimental results under severe multipath propagation conditions will be presented to show the superior ranging and multipath estimation performances of the proposed method over several state-of-the-art techniques.
