Method and apparatus for processing a frequency modulated (FM) signal using an adaptive equalizer |
摘要 |
Embodiments of the present invention relate generally to receivers. A frequency modulated (FM) receiver includes an equalizer control unit coupled to receive at least one FM signal quality indicator and provide a control signal based on the FM signal quality indicator. An adaptive equalizer coupled to receive the control signal from the equalizer control unit and an FM signal and provide a filtered FM signal corresponding to the received FM signal. Coefficients of the adaptive equalizer are reset in response to the control signal. Another embodiment relates to a method for processing a frequency modulated (FM) signal. An FM signal is received. At least one FM signal quality indicator is used to provide a control signal. Based on the control signal, the received FM signal is filtered using one of an adaptive filter and a static filter to provide a filtered FM signal.
