Abstract
A packet detecting method includes receiving the wireless signal, generating a local characteristic sequence, acquiring a first cross-correlation result between the wireless signal and the local characteristic sequence, determining if a packet format of the wireless signal is a target packet format according to the first correlation result, generating at least one interference characteristic sequence according to the local characteristic sequence, a signal sampling frequency, and at least one working frequency difference, acquiring a second cross-correlation result between the wireless signal and the at least one interference characteristic sequence, and detecting a center frequency of the wireless signal for determining if a packet of the wireless signal is transmitted through a target channel according to the first correlation result and the second correlation result. The at least one interference characteristic sequence corresponds to at least one interference frequency.
