Abstract: Various aspects for motion detection and/or gesture recognition in a wireless communication device are disclosed, and may include a transmit/receive radio frequency switch including a control input for controlling radio frequency signal routing of the switch from a radio frequency transmit port of the wireless device to an antenna and from the antenna to a radio frequency receive port of the wireless device, a first radio frequency coupler for coupling to the transmit port of the wireless device and for passing of transmit signals from the transmit port to the antenna through the switch, a second radio frequency coupler for coupling to the receive port of the wireless device and for passing of receive signals from the antenna to the receive port through the switch, and a connector for connecting a transmit isolation port of the first coupler to a receive isolation port of the second coupler.

Abstract: A method for inductively coupled communication is described. The method includes determining an operational mode for inductively coupled communication. The method also includes performing the operational mode by combining a transmit power amplifier (PA) output replica and a PA output copy at a signal combining block of a receiver. The PA output replica reflects effects of channel properties. The PA output copy is unaffected by the channel properties.

Abstract: Various aspects for motion detection and/or gesture recognition in a wireless communication device are disclosed, and may include determining whether a source address of a received data packet is a source address of the wireless device, determining whether a process for the motion detection and/or gesture recognition is enabled in the wireless device and processing one or more received signals for the motion detection and gesture recognition occurring in a proximity of the wireless device. The one or more received signals are transmitted from a transmit antenna of the wireless device and received via a receive antenna of the wireless device. The received data packet is carried by at least one of the one or more received signals. The received data packet may be a Bluetooth data packet carrying the source address.
