RECEIVER APPARATUS

摘要

A receiver apparatus wherein even if a lowpass filter, the suppression characteristic of which is not steep, is used in a multicarrier communication, the degradation of reception quality can be suppressed during reception of disturbance waves having a high reception intensity. A filter control part (106) switches the filter characteristics of lowpass filters (103a,103b) in accordance with a pilot symbol amplitude information obtained during an OFDM demodulation process of an OFDM demodulating part (107). In this way, even during the reception of disturbance waves having a high reception intensity, the degradation caused by the disturbance waves can be minimized without using any additional detectors.
