摘要： Provided are an apparatus and method for channel estimation and synchronization in an orthogonal frequency division multiplexing (OFDM)/ orthogonal frequency division multiplexing access (OFDMA) relay system. When data is received through a relay, channel estimation performance deterioration due to propagation delay can be improved in a transparent relay system or a cooperative relay system by extracting pilot signals based on a signal received from transmitters to a mobile station, estimating propagation delay between each of the transmitters, that transmitted the extracted pilot signals, and the mobile station based on the extracted pilot signals and preset reference pilot signals, and estimating a channel between the corresponding transmitter and the mobile station by estimating propagation delay weight of the corresponding transmitter based on the estimated propagation delay. Also, effects of a carrier frequency offset and timing offset of a link between the corresponding transmitter and the mobile station can be removed by storing the existing carrier frequency offset and timing offset of each transmitter, when the mobile station receives a signal, identifying a transmitter that transmitted the signal, and compensating the signal by using the stored carrier frequency offset and timing offset of the identified transmitter.

A downlink frame has plural symbols into which pilot subcarriers are distributively arranged with respect to time and frequency axes. Initial symbol synchronization and initial frequency synchronization are estimated by using a position at which autocorrelation of a cyclic prefix of a downlink signal and a valid symbol of the downlink is maximized, and cell search and integer-times frequency synchronization are estimated by using pilot subcarriers included in the estimated symbol. Fine symbol synchronization, fine frequency synchronization, and downlink frame synchronization is estimated by using an estimated cell search result. Downlink frequency and time tracking is performed, cell tracking is performed by using a position set of pilot subcarriers inserted into the downlink frame, fine symbol synchronization tracking and fine frequency synchronization tracking are repeated by using the pilot subcarriers to perform the frequency and time tracking of the downlink frame.

摘要： In an OFDMA-based cellular system, a frame of a downlink signal includes a common slot and traffic slots. The common slot includes a synchronization preamble and a cell search preamble. The synchronization preamble has a structure for synchronizing time and frequency, and the cell search preamble has a cell search structure. The traffic slot includes pilot symbols provided on the time and frequency axes. A cyclic prefix is used to estimate initial symbol synchronization, and the initial symbol synchronization and the synchronization preamble are used to synchronize the frame. The synchronization frame and the cell search preamble are used to estimate time and frequency synchronization. The cell search preamble is used to search cells. When the initial synchronization is performed, the cyclic prefix is used to track the frequency, the synchronization preamble is used to track symbol synchronization, and the cell search preamble is used to track fine frequency synchronization.
