GPS application and simulation in multipath environment

Abstract

The focus of this thesis is on the process of exploiting the GPS spread spectrum signal in GPS receiver. After describing the spread spectrum fundamentals, this thesis describes the architecture and functions of civilian GPS receivers and then focuses on performance consideration. The fundamental measurements carried out in the receiver are described and the qualities of these measurements are related to the aforementioned receiver architecture. In addition, the fundamentals of satellite navigation and GPS system segments also described. In this work, a simplified model is developed for the GPS system. The developed Matlab model is used for studying delay estimation algorithms in multipath environment. /Kir10
