摘要:
An apparatus for transmitting a synchronization signal using a plurality of transmit (Tx) antennas is provided. The apparatus includes a synchronization signal generator for generating a synchronization signal used for tracking timing or frequency synchronization, a transmission processor for allocating different subcarriers to a plurality of Tx antennas without overlapping, mapping the synchronization signal to the subcarriers, and generating an orthogonal frequency division multiplexing (OFDM) symbol by performing inverse fast Fourier transformation (IFFT), a control signal coupler for controlling codes as a resource not to overlap among the plurality of Tx antennas, and the plurality of Tx antennas for transmitting the OFDM symbol.
