Abstract
There is provided a device for detecting LTE frame synchronization, including: a CP correlator calculating a correlation of a cyclic prefix (CP) included in each orthogonal frequency division multiplexing (OFDM) symbol of an LTE signal processed digital conversion; a frequency offset compensation unit compensating a frequency offset for a synchronization signal in the LTE signal by using a symbol frequency offset calculated based on the CP correlation; a synchronization signal correlation calculation unit performing a correlation calculation in a time domain with respect to the synchronization signal, of which the frequency offset is compensated, by considering a symbol start timing obtained based on the CP correlation; and a frame synchronization detection unit detecting the frame synchronization of the LTE signal based on a result of the correlation calculation for the synchronization signal.
