Abstract
A method applied to a receiver of a wireless network for determining an unknown quantity of antennas of a transmitter according to a received network is provided. The method includes: delaying the network signal according to a sum of a reference period and an estimated shift interval to provide a delayed signal; calculating a correlation between the network signal and the delayed signal to generate a correlation index; comparing the correlation index and a threshold to provide a comparison result; and determining the unknown quantity of transmitting antennas according to the comparison result.
