SYNTHESIS LECTURES ON COMMUNICATIONS MULTIPAT...

Autonomous vehicles use global navigation satellite systems (GNSS) to provide a position within
a few centimeters of truth. Centimeter positioning requires accurate measurement of each
satellite's direct path propagation time. Multipath corrupts the propagation time estimate by
creating a time-varying bias. A GNSS receiver model is developed and the effects of multipath
are investigated. MATLABtm code is provided to enable readers to run simple GNSS receiver
simulations. More specifically  GNSS signal models are presented and multipath mitigation
techniques are described for various multipath conditions. Appendices are included in the
booklet to derive some of the basics on early minus late code synchronization methods. Details
on the numerically controlled oscillator and its properties are also given in the appendix.
