RECEIVER IN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM AND SIGNAL PROCESSING METHOD THEREOF |
摘要 |
PURPOSE: A receiver in an OFDMA(Orthogonal Frequency Division Multiple Access) system and a signal processing method thereof are provided to reduce the power consumption of a terminal. CONSTITUTION: An extracting unit(440) extracts a user signal vector about a sub-carrier allocated to a receiver from a reception signal vector received from a transmitter. An FFT(Fast Fourier Transform) unit(450) performs FFT of the user signal vector. The extracting unit extracts the user signal vector by a circular convolution of the reception signal vector and the extracted user signal vector. [Reference numerals] (410) Sampling unit; (420) A/D conversion unit; (430) S/P conversion unit; (440) Extracting unit; (450) FFT unit; (460) Symbol extracting unit;
