Wireless Communications

Advanced Topics Lab

 


Practical Subject: Advanced Topics Lab and Seminar


The students acquire the ability to do a literature research on a given scientific topic, to evaluate this literature, to extract central points, and to present a scientific topic in a talk as well as a paper. Furthermore, the students shall be competent to implement their topic in a high-level language (e.g., Java, Matlab or
C/C++). The students are able to work in a team.

Propagation modeling of MIMO Systems (WS1011)

 

To achieve better data transfer rates in future wireless communication systems multiple antenna systems are considered (e.g. LTE (the successor of UMTS)).

Subject of this project is the design of simple communication links with respect to multiple antenna systems. Therefore the physical links aspects are investigated and characteristic properties are illustrated.

For modeling and visualization the program MatLab will be used.

 

The basic points of our "Advanced Topics Lab" are:

  • Wireless communications,
  • Antennas and electromagnetic wave propagation,
  • and the handling of MatLab.

Ultra Wideband Antennas (WS0910)

 

The use of Ultra WideBand (UWB) systems, e.g. for wireless multimedia data communication between different home entertainment systems (DVD player, flat screen, Internet PC, ...) becomes very appealing since the FCC released the spectrum from 3.1 GHz to 10.6 GHz for unlicensed low-power use. Antennas capable of supporting such a broadband frequency range typically consist of smoothly tapered sections (e.g. bow-tie antenna, Vivaldi antenna, etc). Such shapes can be easily defined by analytic functions. This project aims on the electromagnetic modeling of such antennas using state of the art software tools. It includes:

  • Literature survey on UWB antennas
  • Introduction into numerical EM modeling using the EMPIRE XCcel software
  • Programming of Python based templates to generate the antenna shapes
  • Programming of MatLab templates for the characterization of the antennas
  • Antenna design
  • Presentation
