Abstract: PURPOSE: A method for detecting a signal for a wireless communication network based on an OFDMA having different delay time and an apparatus thereof are provided to minimize an interference effect in a wireless communication network by determining an optimal FFT(Fast Fourier Transform) window start location according to each subcarrier. CONSTITUTION: An RF processing unit(400) includes a front end unit and a filter, etc. An ADC(402) changes an analog base band signal of the RF processing unit into a digital signal. A FFT(Fast Fourier Transform) operation unit(404) outputs a signal of a frequency domain by calculating the digital signal in fast fourier transformation. The FFT operation unit performs FFT calculation with the control of a FFT window controller(406). A communication device acquires symbol synchronization, removes CP(Cyclic Prefix), and parallely changes data outputted from the ADC. A FFT window start positioning unit(408) determines a FFT window start location for each subcarrier.
