Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): The growth of wireless communication relies on the availability of radio frequency for new services.
More efficient spectrum allocations are required to serve the increasing data per user.
The major regulatory bodies are formulating new spectrum management techniques to forge the growing spectrum scarcity.
Exclusive use of spectrum is proved to be inefficient in many spectrum occupancy measurement campaigns.
As a result, spectrum sharing methods are being considered.

TV broadcasting is not using the allocated frequency in some geographic areas, creating coverage holes known as TV white spaces.
Both the industry and the regulators are investigating the capability of TVWS, as a potential source of spectrum for emerging wireless services.
The FCC, in the US, has already released the requirements for opportunistic access to the TV whites paces.
In a similar fashion, ECC, the pan-European regulator is finalizing the work on the technical and operational requirements for the possible use of cognitive radio in this spectrum.

In this thesis work, an integrated web-based spectrum availability assessment tool is developed for Finland.
The tool is a front-end visualization of a time intensive computational process to answer key technical questions related to TVWS - what secondary data rate can be supported in the available white space spectrum?
The assessment involves estimation of the available TVWS and its capacity for cellular-type secondary systems.
The relative effects of the secondary system parameters on the TV system are compared using appropriate signal to noise and interference ratio plots.
The tool uses dynamic web technologies for a seamless and user-friendly visualization of the assessment.
