METHOD AND APPARATUS FOR RECEIVING DIVERSITY OF CODED OFDM SIGNAL IN FADING CHANNEL

摘要

PPROBLEM TO BE SOLVED: To provide a method and an apparatus for receiving a COFDM signal by using a plurality of receiving antennas having low complicatedness and to provide a method and an apparatus for improving the accuracy of time synchronization in a diversity receiver and performing automatic gain control (AGC) in the diversity receiver. PSOLUTION: The method and the apparatus for receiving a coded orthogonal frequency division multiplex (COFDM) signal are provided. A COFDM receiver includes a plurality of receiving antennas and provides a plurality of copies of each received signal. A signal received by each antenna is down-converted from radio frequency (RF) to baseband frequency (BF). Respective BF signals from the plurality of receiving antennas are composed before executing fast Fourier transform (FFT). PCOPYRIGHT: (C)2007,JPO&INPIT
