Titel / Title: A Deterministic Channel Model for Simulation of Mobile Radio Communications

Abstrakt Abstract:

The last decade there has been an enormous expansion in the area of wireless
communication. As new services and devices are introduced, and more information
is sent between an increasing number of users, more bandwidth is required
and the spectrum becomes more limited. To increase capacity in cellular networks,
cells can be made smaller and smaller. To be able to plan picocells, such
as an indoor environment, in an efficient manner, it is important to have a more
detailed understanding about the channel characteristics. Further ways to improve
radio communication is to make use of more efficient encoding and receiving
techniques, such as spread spectrum. Also when testing new techniques, knowledge
about the channel characteristics and limitations are of interest.
This thesis models the channel characteristics of an indoor deterministic environment
with a simulator using ray tracing techniques. To make the environment as
realistic as possible, the physical properties of construction materials are taken
into account. The simulator is able to track each individual radio wave, making
it possible to calculate interesting parameters such as received power, phase, and
direction-of-arrival. The simulator operates in 2D-environments. A lot of work
have been done to extend the simulator to a 3D-version, although some problems
still remains to be solved.
