Abstract
The aim of this thesis is to find an a ordable and upgradeable manner of increasing the data
rate of current satellite systems. The compression, modulation and amplification techniques and
telecommunication regulations restrict the data rate, which are bypassed by designing a parallel
channel configuration.
In order to test this solution a system is developed that is based on the existing standards of
DVB-S and MPEG-2. The combination of these standards protect the data from interference,
package the data for ease of storage, modulate the data to more effectively radiate the signal and
shape the spectrum to adhere to telecommunication regulations.
The spacing between the channels is reduced and the transmitted signal is amplified to inject interference
into the system. The effect of this interference on the receiver is shown by transmitting
image data and comparing the received image with the original.
