Web21 jun. 2024 · Gardner timing detector was designed to solve timing errors (such as carrier/sampling frequency offset) between transmitter and receiver. Gardner timing … Web7 jan. 2024 · Usually you have to synchronize timing first because most carrier phase error detectors relay on sampling the transmitted symbols. The early-late method is just one method of timing error detection, and there are many others. Any detector that reliably provides a usable error curve can be used to feed a timing control loop.
