Abstract
An apparatus includes a radio-frequency (RF) receiver, which includes an automatic gain-control (AGC) circuit to use a gain signal to set a gain of front-end circuitry of the RF receiver. The RF receiver further includes an interference-detection circuit to use a value of the gain signal to detect an interference signal.
Claims20
An apparatus, comprising:
- a radio-frequency (RF) receiver, comprising:
- a packet handler circuit to provide an indication of detection of a synchronization word (sync word);
- and
- an interference-detection circuit to use a value of a gain signal and a received signal strength indicator (RSSI) value of the RF receiver and the indication of detection of the sync word to detect a co-channel interference signal and an out-of-band interference signal, wherein the gain signal is used to set a gain of front-end circuitry of the RF receiver.
1 more element
A method of operating a radio-frequency (RF) receiver, the method comprising:
- using a packet handler circuit to provide an indication of detection of a synchronization word (sync word);
- and
- using a value of a gain signal and a received signal strength indicator (RSSI) value of the RF receiver and the indication of detection of the sync word in an interference-detection circuit to detect a co-channel interference signal and an out-of-band interference signal, wherein the gain signal is used to set a gain of front-end circuitry of the RF receiver.
