Abstract
A receiving apparatus which appropriately selects one out of a plurality of antennae for reception. The receiving apparatus is provided with a reception means for receiving a radio wave via an antenna selected out of the plurality of antennae by a selection means, a reception level signal creation means for creating a reception level signal indicative of reception electric field strength for the received radio wave, an extraction means for eliminating the basic wave components of the radio wave from the reception level signal to create the multiple propagating components of the radio wave in the reception level signal as a multiple propagating wave strength signal, and a reception level signal correction means for correcting the reception level signal by using the multiple propagating wave strength signal to create a corrected reception level signal without the multiple propagating wave components. The antenna selection means obtains the corrected reception level signal for the antennae by selecting the antennae in order in response to a reception start of the reception means, and selects an antenna with the corrected reception level signal of the highest signal level.
