Abstract: A method of generating a transmission signal may include mixing a baseband signal assigned for transmission within a narrow frequency range (“assigned narrow frequency range”) included in a wireless communication channel to produce a shifted signal. The shifted signal may have a shifted frequency that is based on a shift from the assigned narrow frequency range toward a center frequency of the wireless communication channel by a frequency offset. The method may further include shifting a modulation frequency of a modulating signal toward the assigned narrow frequency range frequency range and away from the center frequency by the frequency offset. Additionally, the method may include mixing the shifted signal with the modulating signal to produce a transmission signal having a transmission frequency within the assigned narrow frequency range.

Abstract: In accordance with some embodiments of the present disclosure, a control path for a wireless communication device may include a radio frequency coupler having a coupled port and a terminated port, the radio frequency coupler configured to couple at least a portion of a transmission power of a transmission line coupled to the antenna tuner such that the coupled port carries a first signal indicative of an incident power transmitted to an antenna coupled to the antenna tuner and the terminated port carries a second signal indicative of a reflected power reflected by the antenna. the control path may also include a control module configured to communicate the one or more control signals to the antenna tuner for controlling the impedance of the antenna tuner based at least on the first signal and the second signal.

Abstract: Techniques are disclosed for providing isolation between a pair of partially overlapping antennas. An example electronic device includes a first antenna coupled to a first transceiver through a first signal path comprising a first feed, and a second antenna coupled to a second transceiver through a second signal path comprising a second feed. The first antenna and second antenna partially overlap. The example electronic device also includes compensation circuitry coupled to the first signal path and the second signal path and configured to generate a compensation signal that provides analog cancellation of an interference signal received at the second antenna from the first antenna.
