Abstract: A radio receiver may determine whether a received frequency modulated radio signal includes interference from an adjacent channel. The receiver may compare a frequency deviation above the center frequency of the received signal to a frequency deviation below the center frequency of the received signal. The receiver determines that the radio signal is affected by adjacent channel noise when the frequency deviation below the center frequency is substantially different from the frequency deviation above the center frequency. Alternatively, the presence of noise from an adjacent channel may be detected by comparing a positive amplitude and a negative amplitude of a demodulated version of the frequency modulated radio signal. In this alternative, the receiver determines that the radio signal is affected by adjacent channel noise when the extent of the positive amplitude is substantially different from the extent of the negative amplitude.

Abstract: A processing front-end for FM radio signals includes a receiver, a filter, and a mixer. The receiver obtains an FM radio signal including data content centered at a data frequency and programming content. The filter is coupled to the receiver and removes the programming content from the FM radio signal. The mixer accepts the filtered FM radio signal and shifts the center frequency of the data content to a lower frequency than the first frequency. The lower frequency is selected according to a sampling rate available in an analog-to-digital converter present in a subsequent processing stage, typically a low cost digital signal processor.
