Abstract
A carrier control loop (,) for a receiver of digitally transmitted signals is disclosed comprising, in the direction of signal flow, a quadrature demodulator (,), a symbol recognition device (,), a detector (,) for forming a phase deviation value (&phgr;d) and/or a frequency deviation value (fd), a feedback device (,), and a variable-frequency oscillator (,) connected to the quadrature demodulator (,). An evaluating device (,) determines from signals (I, Q) of the carrier control loop (,) a reliability value (z) for the measured phase deviation value (&phgr;d) and/or frequency deviation value (fd), and controls the carrier control loop (,) in accordance with the determined reliability value.
