Abstract

A pilot-based method of extracting and cancelling system caused pilot jitter (SCPJ) in broadcasting systems is introduced and analyzed. It was demonstrated that, by using a wideband pilot extraction system instead of the frequently used minimal bandwidth one, the system performance can be improved considerably. Analytical results for the CNR degradation of a 16-QAM system operated in the presence of sinusoidal SCPJ were obtained as a function of the extraction filters bandwidth, as well as their amplitude and group delay distortions. It was shown that to achieve efficient SCPJ cancellation, it is important to compensate for both of these distortions. However, as far as implementation issues are concerned, group delay distortion seems to be a more prominent source of degradation
