Original Abstract Submitted

An apparatus with a first branch and a second branch that is configured to receive a first signal and a second signal from a same device, where the second signal indicates the apparatus to enter a connected state. The first branch includes a first frequency-amplitude converter configured to obtain first amplitude information of a third signal which is obtained by performing frequency mixing on the first signal and a first local oscillator signal. The second branch is configured to demodulate a fourth signal which is obtained by performing frequency mixing on the second signal and a second local oscillator signal which is obtained by performing frequency offset correction on the first local oscillator signal based on the first amplitude information, the second branch includes a second frequency-amplitude converter, and a linear working interval of the second frequency-amplitude converter is smaller than that of the first frequency-amplitude converter.
