Abstract
A method for detecting a radio signal in a wireless communication system is provided. According to the method, a wireless device measures an input signal received by a RF unit of. The wireless device eliminates a duplicated part between the input signal and a complex conjugate signal of the input signal to generate a filtered signal. The wireless device determines whether a target signal exists in the input signal based on the filtered signal.
Claims15
A method for detecting a radio signal in a wireless communication system, the method comprising:
- measuring, by a wireless device, an input signal received by a RF unit of the wireless device;
- eliminating, by the wireless device, a duplicated part between the input signal and a complex conjugate signal of the input signal to generate a filtered signal;
- and
- determining, by the wireless device, whether a target signal exists in the input signal based on the filtered signal.
A wireless device in a wireless communication system, the wireless device comprising:
- a radio frequency (RF) unit for receiving a radio signal;
- and
- a processor, operatively coupled with the radio frequency unit, configured to:
- measure an input signal received by the RF unit;
- eliminate a duplicated part between the input signal and a complex conjugate signal of the input signal to generate a filtered signal;
- and
- determine whether a target signal exists in the input signal in the input signal based on the filtered signal.
