Satellite data transmission by means of a multi-channel system

[摘要] The aim of this thesis is tofind an a ordable and upgradeable manner of increasing the datarate of current satellite systems. The compression, modulation and amplification techniques andtelecommunication regulations restrict the data rate, which are bypassed by designing a parallelchannel configuration.In order to test this solution a system is developed that is based on the existing standards ofDVB-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 andshape the spectrum to adhere to telecommunication regulations.The spacing between the channels is reduced and the transmitted signal is amplified to inject interferenceinto the system. The effect of this interference on the receiver is shown by transmittingimage data and comparing the received image with the original.
