Abstract:
A reception apparatus and method are provided for acquiring code timing by receiving pilot signals spread with allocated codes in a receiver using multiple antennas, wherein a transmitter using multiple antennas allocates different codes to pilot signals for transmitting through the respective antennas. The apparatus and method comprise receiving the spread pilot signals through the respective antennas; outputting estimated propagation delay values of the pilot signals transmitted from the respective antennas of the transmitter and peak values of matched filters for respective channels; and calculating new estimated propagation delay values by applying weights determined based on the peak values of matched filters for respective channels to the estimated propagation delay values, and acquiring code timing with the new estimated propagation delay values.
