A method for performing near-field communication (NFC)-type operations in the far-field region using a repurposed antenna is described. The method includes determining whether to perform NFC-type operations in a near-field mode or a far-field mode. The method further includes performing NFC-type operations outside a near-field region using a repurposed antenna when in the far-field mode.

Systems and methods for far-field communication using a repurposed antenna

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.

Systems and methods for multi-mode inductively couples communication

A system and method for calibrating digital pre-distortion in a wireless device. A pre-distortion circuit may output a first training signal while a power amplifier of the wireless device is on, to generate a first feedback signal. The first feedback signal may be fed back to the pre-distortion circuit via a receive path of the wireless device. The pre-distortion circuit may output a second training signal while the power amplifier is off, to generate a second feedback signal. The second feedback signal may be fed back to the pre-distortion circuit via the receive path. The pre-distortion circuit may then determine one or more pre-distortion coefficients based on the first and second feedback signals.
