Faculty Profile

Dr. Yao’s research focuses on using signal processing techniques to tackle satellite navigation and positioning problems. It mainly targets new GNSS signals design, optimization, and processing, but also investigates personal and vehicular positioning in challenging environments such as urban canyons and strong multipath environments. The domains of research and expertise are:

• Spreading modulation and multiplexing techniques for GNSS;

• Software-defined multi-GNSS real-time receiver

• Split-spectrum DSSS signals unambiguous acquisition and tracking;

• Ground-based high precision navigation system;

• GNSS signals multipath mitigation techniques;

• Cooperative positioning in signal level;
