Multicarrier modulation schemes have an increasing role in digital broadcasting
systems.. Many system - including DAB, DVB-T and LTE - use the OFDM (Orthogonal
Frequency Division Multiplexing) method for transmission.
In my BSc thesis I give a brief overview on the elements of wireless communication
systems, such as transciever, channel and reciever. Afterwards I introduce a
specic digital modulation technique, OFDM with a detailed description of such system's
features. I discuss the time- and frequency domain waveforms used in OFDM
devices, the distortion caused by the channel and the role of analog devices. The
compensation of the non-ideal behaving is also discussed.
After going through the theoretical background, my aim is to create an engineers
model of the system. I use Matlab as environment for the model. With my software,
it is possible to run simulations with various input parameters. A conclusion can be
drawn on the system's properties based on the results of the simulation.
In my diploma thesis I discuss the construction of the model, the formation and
operation of the simulator. Finally I draw the conclusion from the results of the
