Abstract
A packet detection method is disclosed. The packet detection method includes the following operations: receiving a wireless communication signal; calculating a delay correlation function of the wireless communication signal; calculating a delay related output value and a threshold value according to the delay correlation function; and determining whether the wireless communication signal satisfies a feature of a wireless network packet or not according to the delay related output value and the threshold value.
