Abstract
In an OFDM receiver with a diversity configuration having a plurality of demodulation modules, to perform FFT window position recovery and clock recovery, the gain values calculated by the AGC units () provided in the demodulation modules for adjusting the level of the received signal are supplied to a correlation combiner (); the correlation combiner () multiplies the correlation signals supplied from the correlation detectors () in the demodulation modules by coefficients calculated from the gain values, then adds the products to generate a combined correlation signal and supplies it to an FFT window position recovery unit () and a clock error detector (). FFT window position recovery and clock recovery can thus be performed properly without depending on any one demodulation module.
