Claims (6)

デジタル信号で変調された電波を受信する受信装置であって、A receiving device for receiving radio waves modulated with a digital signal,
複数の受信信号のうち少なくとも１つの受信信号を選択する選択部と、A selection unit that selects at least one received signal among a plurality of received signals;
前記選択部により選択された受信信号の受信状態に基づいて該選択部を制御する制御部と、を備え、A control unit that controls the selection unit based on the reception state of the reception signal selected by the selection unit,
前記制御部は、受信状態が悪化した場合、受信信号の受信レベルが所定の基準値以下の受信信号を選択することを特徴とする受信装置。When the reception state deteriorates, the control unit selects a reception signal whose reception level is lower than a predetermined reference value. 複数のアンテナからなるアンテナ群を有し、It has an antenna group consisting of multiple antennas,
前記選択部は、前記アンテナ群の少なくとも1つのアンテナを選択することにより、前記少なくとも１つの受信信号を選択し、The selection unit selects the at least one received signal by selecting at least one antenna of the antenna group;
前記制御部は、受信状態が悪化した場合、受信信号の受信レベルが所定の基準値以下のアンテナを選択することにより、前記受信信号を選択することを特徴とする請求項１記載の受信装置。The receiving apparatus according to claim 1, wherein when the reception state deteriorates, the control unit selects the reception signal by selecting an antenna whose reception level of the reception signal is a predetermined reference value or less. 前記制御部は、前記選択部により選択されたアンテナで受信した信号を受信状態悪化と判定したとき、該選択されたアンテナで受信した信号の受信レベルを取得し、該取得した受信レベルが所定の基準値より大きい場合に、前記受信レベルが所定の基準値以下のアンテナを選択することを特徴とする請求項２記載の受信装置。When the control unit determines that the signal received by the antenna selected by the selection unit is deteriorated in the reception state, the control unit acquires a reception level of the signal received by the selected antenna, and the acquired reception level is a predetermined level. 3. The receiving apparatus according to claim 2, wherein an antenna having a reception level equal to or lower than a predetermined reference value is selected when the reference level is larger. 前記アンテナ群は、無指向性アンテナと複数の指向性アンテナとからなり、The antenna group consists of an omnidirectional antenna and a plurality of directional antennas,
前記制御部は、前記無指向性アンテナ選択時に受信悪化と判定したとき、該無指向性アンテナで受信した信号の受信レベルを取得し、該取得した受信レベルが所定の基準値よりも大きい場合に、前記受信レベルが所定の基準値以下の指向性アンテナを選択することを特徴とする請求項２記載の受信装置。When the control unit determines that reception is deteriorated when the omnidirectional antenna is selected, the control unit acquires a reception level of the signal received by the omnidirectional antenna, and the acquired reception level is greater than a predetermined reference value. 3. A receiving apparatus according to claim 2, wherein a directional antenna having a reception level equal to or lower than a predetermined reference value is selected. 前記アンテナ群は、複数の指向性アンテナから構成されるとともに、該複数の指向性アンテナの合成により無指向性アンテナを構成し、The antenna group is composed of a plurality of directional antennas, and constitutes an omnidirectional antenna by combining the plurality of directional antennas.
前記制御部は、前記無指向性アンテナ選択時に受信悪化と判定したとき、該無指向性アンテナで受信した信号の受信レベルを取得し、該取得した受信レベルが所定の基準値よりも大きい場合に、前記受信レベルが所定の基準値以下の指向性アンテナを選択することを特徴とする請求項２記載の受信装置。When the control unit determines that reception is deteriorated when the omnidirectional antenna is selected, the control unit acquires a reception level of the signal received by the omnidirectional antenna, and the acquired reception level is greater than a predetermined reference value. 3. A receiving apparatus according to claim 2, wherein a directional antenna having a reception level equal to or lower than a predetermined reference value is selected. 前記制御部は、前記選択部により選択されたアンテナで受信した信号を受信悪化と判定したとき、前記選択されたアンテナで受信した信号の受信レベルを取得し、該取得した受信レベルが所定の基準値よりも大きい場合に、該選択されたアンテナとは逆方向の指向性のアンテナを選択することを特徴とする請求項２記載の受信装置。When the control unit determines that the signal received by the antenna selected by the selection unit is deteriorated in reception, the control unit acquires a reception level of the signal received by the selected antenna, and the acquired reception level is a predetermined reference 3. The receiving apparatus according to claim 2, wherein when the value is larger than the value, an antenna having a directivity opposite to the selected antenna is selected.
