DIVERSITY RECEIVER, AND METHOD FOR RECEIVING ORTHOGONAL FREQUENCY DIVISION MULTIPLEX SIGNAL

摘要

A diversity receiver capable of stably receiving an orthogonal frequency division multiplex signal, wherein a demodulator is so operated that the attenuation of the received signal is varied step by step every time a period corresponding to a guard interval section comes if it is determined that the reception level is increased by switching the attenuation in any one of variable attenuators, and the demodulator is so operated that the variable attenuator designated by an antenna control pointer is changed and the attenuation is varied if it is determined that the variable attenuator designated by an antenna control pointer is identical with the variable attenuator designated by an antenna fixing pointer.
