Abstract
A method and apparatus for selecting a channel of an NFC signal are provided. The method includes: determining first and second envelope signals respectively according to an I-channel signal and a Q-channel signal in the NFC signal, determining a first reference point and a first demodulation threshold corresponding to the first reference point according to the first envelope signal, determining a second reference point and a second demodulation threshold corresponding to the second reference point according to the second envelope signal, determining first and second bit count values by performing first and second bits count respectively on the first and second envelope signals, and determining a target-channel signal from the I-channel signal and the Q-channel signal according to the first and second bit count values, if the first or second bit count value reaches a preset bits threshold.
