Satellite data transmission by means of a multi-channel system
Thesis (MEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2006.
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.
