Adaptive frame synchroniser for digital satellite communication systems

The paper presents an analysis of the error performance of a basic frame synchroniser when noise and timing uncertainties exist. The results yield criteria for a new window width and detection threshold strategy, and a new form of frame synchroniser for digital satellite communication systems is described. It is shown that false alarms and misdetections may be minimised using the adaptive window width and adaptive detection threshold strategies implemented using a microprocessor-based system.
