Abstract
PURPOSE: A method of transmitting a control signal in a wireless communication system is provided to improve the reliability of detecting a coherent signal by minimizing an orthogonal damage generated in a de-spreading process. CONSTITUTION: A transmitter(100) comprises a DFT part(110) performing the DFT(Discrete Fourier Transform) and an IFFT part(120) performing the IFFT(Inverse Fast Fourier Transform). The DFT part processes DFT of inputted data and outputs a frequency domain symbol. The Data inputted to the DFT part corresponds to the control signal and/or user data. The IFFT outputs the transmission signal by process IFFT of the inputted frequency domain symbol. The time domain symbol of the IFFT part corresponds to the OFDM(Orthogonal Frequency Division Multiplexing) symbol or the SC- FDMA(Single Carrier-Frequency Division Multiple Access) symbol.
