Blind-Equalised and Turbo Coded Satellite Based Digital Video Broadcasting
Blind-Equalised and Turbo Coded Satellite Based Digital Video Broadcasting
The Pan-European Digital Satellite Video Broadcasting (DVB-S) system's performance is characterised. Various configurations of blind equalisers and convolutional codecs operating at different code rates were investigated. The standard system's performance was improved upon replacing the conventional convolutional codec by a turbo codec. Lastly, the feasibility of employing 16-level Quadrature Amplitude Modulation (16-QAM) within the DVB-S system is demonstrated, potentially doubling the available bitrate hence improving the associated video quality at the cost of a higher Signal-to-Noise Ratio (SNR) requirement. This extra transmitted power requirement can be eliminated upon invoking a similar complexity turbo codec, which requires lower transmitted power for attaining the same performance as the standard convolutional codes.

Abstract
The Pan-European Digital Satellite Video Broadcasting (DVB-S) system's performance is characterised. Various configurations of blind equalisers and convolutional codecs operating at different code rates were investigated. The standard system's performance was improved upon replacing the conventional convolutional codec by a turbo codec. Lastly, the feasibility of employing 16-level Quadrature Amplitude Modulation (16-QAM) within the DVB-S system is demonstrated, potentially doubling the available bitrate hence improving the associated video quality at the cost of a higher Signal-to-Noise Ratio (SNR) requirement. This extra transmitted power requirement can be eliminated upon invoking a similar complexity turbo codec, which requires lower transmitted power for attaining the same performance as the standard convolutional codes.
