Abstract
Receiver for receiving a received signal with a carrier frequency loop () which generates a carrier frequency deviation detection signal (TF) for detecting a carrier frequency of the received signal in a first carrier frequency capture range; a carrier phase loop () which generates a carrier phase deviation detection signal (TP) for detecting a carrier phase of the received signal, and settles when the carrier frequency deviation detection signal (TF) is within a second carrier frequency capture range; and with an offset control circuit () which changes the carrier frequency deviation detection signal (TF) and/or changes the second carrier frequency capture range by means of an offset control signal until a carrier phase lock detection circuit () indicates to the offset control circuit that the carrier phase offset of the received signal is less than an adjustable threshold value.
