Abstract: In a serial communication system having a device including a receiver detection module, this specification is directed to systems and methods for selectively reducing the power consumed by the receiver detection module, preferably when the device is operating in a low power mode. In some embodiments, a signal detection module is configured to receive a control signal from the transmitter of a device at the other end of the communications link to control the operation of the receiver detection module. The control signal may be in-band or may be transmitted on a sideband of the serial link.

Abstract: A method and apparatus are disclosed for a wireless communication device capable of scanning for radar signals while detecting and/or receiving a wireless communication signal. The wireless communication device may include a plurality of local oscillator synthesizers to allow distinct frequency bands to be used for wireless communication signals and radar detection. In some embodiments, the wireless communication device may include a radar detection physical layer (PHY) circuit to detect the presence of radar signals within a received RF signal. The radar detection PHY may have limited functionality suitable primarily for radar signal analysis and not suitable for processing (decoding) communication signals.

Abstract: A wireless communications device that produces phase-synchronized local oscillator (LO) signals. The device includes a first transceiver chain to receive a first timing signal and a second transceiver chain to receive the first timing signal and a second timing signal. The first transceiver chain includes a first frequency divider to convert the first timing signal to a first LO signal. The second transceiver chain includes a multiplexer to select one of the timing signals based at least in part on a mode select signal. A second frequency divider in the second transceiver chain converts the selected timing signal to a second LO signal, and a phase alignment circuit aligns a phase of the second LO signal with a first alignment signal. The first alignment signal is activated, for a limited duration, in response to a change in state of the mode select signal.

Abstract: This disclosure describes techniques for providing active interference cancellation in a wireless communication system having a Bluetooth transmit chain and a WLAN receive chain. A signal sampled from the Bluetooth transmit chain is gain and phase adjusted to offset interference in the WLAN receive chain. A quadrature phase shifter may be used to generate quadrature components of the sampled signal that are selectively combined to achieve a desired phase adjustment. The phase shifter may be stabilized by a variable capacitor. These techniques may be extended to MIMO systems.
