Receiver and method for initial synchronization of a receiver with the carrier frequency of a desired channel

摘要

The invention relates to a receiver and a method for initial synchronization of a receiver with the carrier frequency of a desired channel. It can happen during synchronization that the locally generated frequency can indeed be generated correctly although a divider ratio of a variable frequency divider inside the receiver and the reference frequency of a reference oscillator 3 inside the receiver are simultaneously incorrectly set. The incorrect setting is evident in a particularly large skew which is detected in the receiver. In order to avoid such faulty settings even when use is made of budget-priced reference oscillators with relatively large frequency deviations, the skew is evaluated in the receiver and, should a prescribed threshold value be exceeded, a second and a third control signal are generated in order to correct the divider ratio and the reference frequency.
