APPARATUS AND METHOD FOR REMOVING A DC OFFSET IN A WIRELESS COMMUNICATION SYSTEM, PARTICULARLY FOR REMOVING A DC OFFSET BY UTILIZING A PERIODIC CP(CYCLIC PREFIX) SECTION

摘要

PURPOSE: An apparatus and method for removing a DC offset in a wireless communication system are provided to enhance the quality of a reception signal in an activating state of an RFIC(Radio Frequency Integrated Circuit) by updating an SDRAM based on the data stored in an RFIC command memory.;CONSTITUTION: A reception terminal of a wireless communication system includes an LNA(Low Noise Amplifier)(100) and a frequency converter(102). In addition, the reception terminal includes a DC compensator(104), an ADC(Analog/Digital Converter)(106-1,106-2), a BPF(Band Pass Filter)(108-1,108-2) and an S/P(Serial to Parallel) converter(110). Furthermore, the reception terminal contains an OFDM demodulator(112) and a DC offset removing device(120).;COPYRIGHT KIPO 2011
