摘要： Disclosed herein is a ranging apparatus and method. The ranging apparatus includes a correlation unit for correlating OFDMA reception signals with inverse fast Fourier transformed ranging codes, and outputting correlation result values. A threshold determination unit determines a threshold value depending on characteristics of the reception signals. A comparison unit estimates a delay time by selecting a maximum value from among the correlation result values, and detects a ranging code by comparing the maximum value with the threshold value, and then outputs and feeds back the ranging code and the delay time when the maximum value is equal to or greater than the threshold value. A weight multiplication unit delays the ranging code by the delay time, multiplies a weight by the delayed ranging code, and outputs a resulting value. A calculation unit subtracts the resulting value from the reception signals, and provides adjusted reception signals.

摘要： Methods and apparatus are provided for transmitting/receiving data in consideration of carrier frequency in the mobile communication system using multiple transmission antennas for increasing data rate and system throughput. A number of antennas and a plurality of symbols are determined via an in-phase domain and a quadrature-phase domain. The symbols are mapped according to the number of antennas and the in-phase domain and the quadrature-phase domain. The mapped symbols are transmitted through corresponding antennas.
