CARRIER TRACKING FOR RADIO RECEIVERS WITH IN-BAND SHARED CHANNEL WITH AMPLITUDE MODULATION Russian patent published in 2011 - IPC H04L27/00 

Abstract RU 2438258 C2

FIELD: information technology.

SUBSTANCE: input signal is received; a local oscillator signal is generated in response to a control signal; the input signal is mixed with the local oscillator signal to create a first signal; the first signal is converted to form a filtered first signal with thinned out sampling frequency; phase error and frequency error of the filtered first signal is detected, normalised for attenuation of fading effects, and an adaptive loop filter for third-order frequency-phase automatic tuning is used to form a control signal in response to the phase error and the frequency error of the filtered first signal.

EFFECT: simple carrier tracking.
