Abstract :
This paper discusses a 16 QAM burst mode receiver system for upstream communication over the CATV network. A prototype is realised in a hybrid analog-digital technology using standard programmable logic components. Efficient data transport is ensured by partially overlapping phase, amplitude and symbol timing recovery during a preamble with fixed content. Important technical issues and measurements are presented
