Abstract: A time synchronization method in an orthogonal frequency division multiplexing (OFDM) system comprises: a coarse time synchronization step of determining the start position of an OFDM symbol by performing coarse time synchronization using correlation of a protection interval of the OFDM symbol of a received signal; and a fine time synchronization step of estimating the fast Fourier transform (FFT) window position of the OFDM symbol by performing fine time synchronization through analysis of channel impulse response (CIR) characteristics of the received signal. Therefore, complexity of time offset estimation can be reduced, and accuracy of offset estimation can be improved.

Abstract: Disclosed are a method, an apparatus, and a system for providing mobile advertisements in a small-scale wireless network. The method for providing mobile advertisements comprises the steps of: receiving an entrance message notifying that a mobile terminal enters a wireless network; receiving an information reception flag inquiring about whether or not to receive information about events near the current location of the mobile terminal, wherein the information about events includes information about discounts; and transmitting the information about events to the mobile terminal according to a response of the mobile terminal to the information reception flag. Therefore, when a subscriber using a mobile device exists in the network, information about ongoing events within the network can be provided for the subscriber through a short message service (SMS) or a mobile phone application. Consequentially, user convenience is improved.
