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): 3GPP includes the LTE air interface specifications in various releases.
Several interesting features such as Home Enhanced Node-B (HeNB) known as femtocells and Coordinated Multipoint Transmission (CoMP) have been introduced.
According to the requirements, Long Term Evolution is expected to provide higher data rates especially at cell edge.

In this thesis, a noteworthy implementation of Coordinated Multipoint Transmission is proposed to fulfill the performance targets of 4G cellular networks.
The coordination takes place in a femtocell network for downlink in this study.
The coordination enhances the signal quality received at the user terminal resulting in an improvement in the indoor coverage, cell capacity, lower CAPEX and enhanced network topology.

This thesis studies the positive and negative aspects of implementation of CoMP in femtocell systems within LTE framework.
The basic work done throughout this thesis is to investigate the parameter configuration and performance evaluation of downlink base station coordination in LTE femtocell scenario. 3GPP's technical specifications are applied for both macrocell and femtocell deployment.
Parameter optimization and performance evaluation are examined for the users in the femtocell from different perspectives.
