Sammendrag
This is a Bachelor’s thesis and is a part of the study program Computer Science at theUniversity of Stavanger. The group decided to write this thesis about Wireless Commu-nication, with a focus on the physical layer, because of the ever-greater popularity it hasachieved and how it is a part of our everyday lives. In order to showcase functionalities,an emulator is a great compromise between simulation and experimentation. With thehelp of such an emulator, this thesis will include various exercises spanning multipletopics that can easily be expanded upon later.
After proposing exercises, the search for a suitable emulator started. Because many ofthese programs are well developed and offer a great variety of functionalities, it leavesthem very costly to use. Thankfully, the University of Stavanger offers its studentsa free license for a great emulator. After an extensive search and comparison for amulti-functional emulator to use for our thesis, we concluded with MATLAB. To showthe different functionalities MATLAB offers, we have created multiple exercises that coverseveral aspects of the physical layer. Some of these include Modulation, Antenna, andPropagation. To highlight one outcome we discovered, in order to achieve a better andmore accurate transmission, it is not as easy as just increasing the number of antennas.
The group decided to start the thesis with less complicated exercises in the beginning, soit will be easier to understand the exercises revolving around antenna later. This thesisis written in a way where it is easy to implement different technologies and showcaseother functionalities later on. This is important because wireless communication neverstops developing and adapting, which means it will always be possible to have up-to-dateunderstandable information This is a Bachelor’s thesis and is a part of the study program Computer Science at theUniversity of Stavanger.
