During the term and the writing of my thesis I first did some research in professional literature, which enhanced my knowledge of the various radio-wave based positioning procedures. I got to know a lot of different and interesting techniques which were all created to locate the user’s geographical position somehow. In my thesis I, as far as possible, described these techniques and procedures in detail.
As a next step of the thesis creation, I got familiar with one of the latest wireless communication technologies, the LTE system, which is considered to be a 4G wireless service and is gaining more and more popularity nowadays. I got an insight into its structure, operation and technical background. As a part of it, I described the techniques dedicated to support the positioning in LTE, such as Positioning Reference Signals (PRS) and the LTE Positioning Protocol (LPP).
In the last part of the thesis, I implemented E-CID, a positioning process used in LTE, into a MATLAB based simulation environment (based on the WINNER II channel model made by the WINNER team). I studied the behaviour and correct operation of my implemented algorithm in different surroundings (urban, suburban and rural surroundings), considering the number of base stations available to locate the position.
The result of all this is an operational algorithm, which can easily be extended and developed.
