PURPOSE: A method for processing an initial ranging signal in a wireless telecommunication system and a method thereof are provided to both an initial ranging channel signal and a data channel signal by using equal sized FFT engines. CONSTITUTION: An apparatus for processing an initial ranging signal includes a ranging signal transmission processing unit(10) and a ranging signal reception processing unit(20). The ranging signal transmission processing unit comprises a ranging signal generating unit(11) generating a ranging signal, a FFT(Fast Fourier Transform) unit(12), and a signal interpolation unit(13). The signal generating unit generates an initial ranging code. The IFFT unit performs the IFFT(Inverse Fast Fourier Transform) calculation of the initial ranging code. The signal interpolation unit performs the signal interpolation of a signal outputted from the IFFT unit. The ranging signal reception processing unit comprises a demultiplexing unit(21), K sized FFTs(22,23), correlators(24,25), initial ranging code generating unit(26), K sized FFTs(27,28), and a peak detector(29).
