A method for the receiver-side recovery and / or readjustment a sampling frequency for adaptation to the sampling frequency of a received signal

摘要

A method is proposed for the recovery and / or readjustment of a first sampling frequency in a receiver for reception with a second sampling frequency sampled, signals transmitted via a transmission channel is formed, characterised in that the received signals in a buffer memory of the receiver are written, that the received signals as a function of the first sampling frequency to be read out from the buffer memory, and in that the first sampling frequency is derived from the filling level of the buffer memory is. The method according to the invention has the advantage of ensuring the receiver clock - recovery also when it is not - isochronous data transmission, of the further an automatic adaptation of a receiver to the timing jitter of a transmitter as well as an automatic adaptation of the receiver to an arbitrary sampling frequency of the transmitter.
