Advancements in Multipath Mitigation for GNSS Receivers: Review of Channel Estimation Techniques

Space: Science & Technology
Multipath interference poses substantial challenges to global navigation satellite system (GNSS) receivers, leading to inaccuracies in the time of arrival (TOA) measurement of the line of sight (LOS) signal. Therefore, to mitigate the impact of multipath
