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): In this thesis the author constructed a mathematical model using a continuous and differentiable expression, that approximates the BLER (Block Error Rate) performance of punctured turbo codes for different (SNR) Signal to Noise ratios, block lengths and MCS (Modulation and Coding Schemes) rates.

The model can be used for two different purposes.
First, the model can be used to replace look-up tables in system level simulators; bringing the advantage of introducing a continuous set of block lengths and MCS rates, not available in look-up tables.
Second, with the help of this function communications systems can be optimized using analytical methods based on differentiation.

The construction of the mathematical model was developed for the particular case of the Turbo Code (13, 15)8 and QPSK modulation; but the derivation of the model can be generalized to other Turbo Codes and modulation types.
The model was also applied to a different link configuration using 16 QAM modulation.
