Abstract
A reception system includes a reception circuit, an antenna element, a cable, a switching circuit, and a control unit. The switching circuit can perform switching between a first connection state in which the reception circuit, the antenna element, and the cable are electrically connected to each other and a second connection state in which the reception circuit and the cable are electrically connected to each other but the antenna element is not electrically connected to the cable. The control unit controls the switching circuit such that the first connection state is obtained in a first time period and the second connection state is obtained in a second time period.
Claims13
A reception apparatus comprising:
- a processor configured to perform predetermined processing on an electrical signal corresponding to a radio signal configured by a preamble portion and a data portion following the preamble portion, the data portion including image data picked up by a mobile body;
- and
- a switching circuit configured to be capable of performing switching between a first connection state in which an antenna element capable of receiving the radio signal receives the radio signal, and a second connection state in which only a cable positioned between the processor and the antenna element and configured to transmit the electrical signal receives the radio signal transmitted by the mobile body, wherein the processor is configured to:
- switch the switching circuit such that the first connection state is obtained in a first time period out of a time period in which the preamble portion is received and the second connection state is obtained in a second time period out of the time period in which the preamble portion is received, the second time period being different from the first time period;
- and
- switch the switching circuit to either the first connection state or the second connection state based on the electrical signal corresponding to the radio signal received in each of the first time period and the second time period in a time period in which the data portion is received.
A reception method of receiving a radio signal configured by a preamble portion and a data portion following the preamble portion, the data portion including image data picked up by a mobile body, the radio signal being transmitted by the mobile body, the reception method comprising:
- switching the switching circuit to a first connection state in which an antenna element capable of receiving the radio signal receives the radio signal in a first time period out of a time period in which the preamble portion is received;
- switching the switching circuit to a second connection state in which only a cable positioned between a processor configured to perform predetermined processing on an electrical signal corresponding to the radio signal and the antenna element receives the radio signal in a second time period out of the time period in which the preamble portion is received, the second time period being different from the first time period, the cable being configured to transmit the electrical signal;
- and
- switching the switching circuit to either the first connection state or the second connection state based on the electrical signal corresponding to the radio signal received in each of the first time period and the second time period in a time period in which the data portion is received.
A reception apparatus configured to receive a radio signal configured by a preamble portion and a data portion following the preamble portion, the data portion including image data picked up by a mobile body, the radio signal being transmitted by the mobile body, the reception apparatus comprising:
- a processor configured to perform predetermined processing on an electrical signal corresponding to the radio signal;
- a reception antenna configured by an antenna element capable of receiving the radio signal, and cable positioned between the processor and the antenna element and configured to transmit the electrical signal;
- and
- a switching circuit capable of performing switching between a first connection state in which the antenna element receives the radio signal and a second connection state in which only the cable receives the radio signal, wherein the processor:
- switches the switching circuit such that the first connection state is obtained in a first time period out of a time period in which the preamble portion is received and the second connection state is obtained in a second time period out of the time period in which the preamble portion is received, the second time period being different from the first time period;
- and
- switches the switching circuit to either the first connection state or the second connection state based on the electrical signal corresponding to the radio signal received in each of the first time period and the second time period in a time period in which the data portion is received.
