Abstract
The present disclosure relates to a receiving device and a receiving method that can receive both signals of a GNSS signal and a wireless LAN at lower cost and more compactly. A selecting unit selects either a received GNSS signal or wireless LAN signal. By multiplying the signal selected in the selecting unit by a local oscillation signal generated in a local oscillation circuit, a converting unit converts the selected signal into an IF signal with lower intermediate frequency. A control unit controls the selecting unit, and performs control so that the GNSS signal and the wireless LAN signal are processed in a time-sharing manner in the converting unit. The technology of the present disclosure can be applied to a receiving device that receives a signal from a GPS satellite, for example.
Claims12
A receiving device, comprising:
- a first receiving unit configured to receive a first GNSS signal, wherein the first GNSS signal is transmitted from a first satellite of a first satellite positioning system;
- a second receiving unit configured to receive a wireless LAN signal, wherein the wireless LAN signal is transmitted from an access point of a wireless LAN;
- a selecting unit configured to select one of the received first GNSS signal or the received wireless LAN signal;
- a local oscillation circuit configured to generate an oscillation signal;
- a converting unit configured to convert the selected one of the received GNSS signal or the received wireless signal into an IF signal with lower intermediate frequency by multiplication of the selected one of the received GNSS signal or the received wireless signal and the oscillation signal;
- and
- a control unit configured to control the selecting unit to process the first GNSS signal and the wireless LAN signal in a time-sharing manner in the converting unit.
A receiving method, comprising:
- in a receiving device:
- receiving, by a first receiving unit of the receiving device, a GNSS signal, wherein the GNSS signal is transmitted from a satellite of a satellite positioning system;
- receiving, by a second receiving unit of the receiving device, a wireless LAN signal, wherein the wireless LAN signal is transmitted from an access point of a wireless LAN;
- selecting, by a selecting unit of the receiving device, one of the received GNSS signal or the received wireless LAN signal;
- generating, by a oscillation circuit of the receiving device, an oscillation signal;
- converting, by a converting unit of the receiving device, the selected one of the received GNSS signal or the received wireless signal into an IF signal with lower intermediate frequency by multiplication of the selected one of the received GNSS signal or the received wireless signal and the oscillation signal;
- and
- controlling, by a control unit of the receiving device, the selecting unit to process the GNSS signal and the wireless LAN signal in a time-sharing manner in the converting unit.
