    Abstract: Signals propagating on an aggressor communication channel can cause interference in a victim communication channel (110, 115). A sensor (125) coupled to the aggressor channel can obtain a sample of the aggressor signal. The sensor (125) can be integrated with or embedded in a system, such as a flex circuit (200) or a circuit board, that comprises the aggressor channel. The sensor (125) can comprise a dedicated conductor or circuit trace that is near an aggressor conductor (120), a victim conductor, or an EM field associated with the interference. An interference compensation circuit (130) can receive the sample from the sensor. The interference compensation circuit can have at least two operational modes of operation. In the first mode, the circuit can actively generate or output a compensation signal that cancels, corrects, or suppresses the interference. The second mode can be a standby, idle, power-saving, passive, or sleep mode.

    Abstract: A wireless communication system can comprise two or more antennas that interfere with one another via free space coupling, surface wave crosstalk, dielectric leakage, or other interference effect. The interference effect can produce an interference signal on one of the antennas. A cancellation device can suppress antenna interference by generating an estimate of the interference signal and subtracting the estimate from the interference signal. The cancellation device can generate the estimate based on sampling signals on an antenna that generates the interference or on an antenna that receives the interference. The cancellation device can comprise a model of the crosstalk effect. Transmitting test signals on the communication system can define or refine the model.
