Title:
ADAPTIVE TIMING SYNCHRONIZATION FOR RECEPTION FOR BURSTY AND CONTINUOUS SIGNALS
Document Type and Number:
WIPO Patent Application WO/2019/057537
Kind Code:
A3
Abstract:
There are provided examples of receivers, controller units (e.g., for the receivers) and related methods (e.g. for the receivers). One receiver is provided which comprises: an adjustable sample provider (604) configured to provide samples of an input signal using an adjustable sample timing; a feedback path (630) configured to provide a feedback signal to the adjustable sample provider (604) on the basis of a timing error (634), wherein the feedback path (630) comprises a loop filter (636) configured to provide sample timing information (638) to the adjustable sample provider (604); and a replacement value provider (640) configured to provide a replacement sample timing information (642) replacing the sample timing information (638) provided by the feedback path (630) when an input signal does not fulfil a predetermined requirement for a feedback-based sample timing adaptation, wherein the replacement value provider (640) is configured to provide the replacement sample timing information (642) considering a timing error information (634), or a quantity derived from the timing error information (634), over a longer time period when compared to a time period considered by the loop filter (636) for a provision of the sample timing information (638).
