Abstract
A computing device can include a radio receiver to receive a radio signal from a radio transmitter of a second computing or communication device. The radio receiver can experience radio frequency interference. The computing device can also include a digital signal generator. The digital signal generator can be to process a signal (S1) underlying a source of the radio frequency interference. The digital signal generator can also be to generate a digital signal (S1). The digital signal generator can further be to inject the digital signal (S1) into the radio receiver to cancel the radio frequency interference around the radio frequency of interest.
Claims21
A computing device, comprising:
- a radio receiver to receive a radio frequency signal from a radio transmitter of a second device,
- the radio receiver to experience radio frequency interference;
- and
- a digital signal generator to:
- process a signal (S0) underlying a source of the radio frequency interference;
- generate a digital signal (S1);
- and
- inject the digital signal (S1) into the radio receiver to cancel the radio frequency interference.
A digital signal generator, comprising:
- a digital signal generator of a computing device, the digital signal generator to:
- process a signal (S0) underlying a source of radio frequency interference;
- generate a digital signal (S1);
- and
- inject the digital signal (S1) into a radio receiver of the computing device experiencing the radio frequency interference to cancel the radio frequency interference.
A computing system, comprising:
- a processor to process a signal (S0) underlying a source of the radio frequency interference;
- logic to generate a digital signal (S1);
- and
- logic to inject the digital signal (S1) into a radio receiver of the computing system experiencing the radio frequency interference to cancel the radio frequency interference.
