摘要：
An apparatus and method are provided for transmitting and receiving a pilot signal using multiple antennas in an OFDM mobile communication system. In the pilot transmitting apparatus, at least one Walsh coverer Walsh-covers a pilot signal to be sent through each of transmit antennas. At least one transmitter allocates the Walsh-covered pilot signals to a predetermined subcarrier in every OFDM symbol and transmits the allocated pilot signals through the transmit antennas.
