Abstract
A frame synchronization method of an embodiment is disclosed. The method includes comparing a preamble arranged at a predetermined position in a received signal with a predetermined signal pattern to calculate a maximum preamble correlation value, using the maximum preamble correlation value to estimate a C/N ratio of the received signal, setting a correlation threshold for frame synchronization detection according to the estimated C/N ratio, and comparing an access address arranged at a predetermined position in the received signal with a predetermined signal pattern to calculate a preamble correlation value, and detecting timing at which the preamble correlation value first exceeds the set correlation threshold as a frame synchronization point.
