  • Self-interference cancellation for in-band full duplex single antenna communication systems
    Patent number: 11356235
    Abstract: An analog self-interference cancellation technique for In-Band Full-Duplex (IBFD) systems generates an inherent secondary self-interference (SI) signal of a circulator and uses that signal to cancel a primary SI signal leaked from a transmitter port within a communication device. The communication device manipulates the phase and angle of this secondary SI, using an adjustable Impedance Mismatch Terminal (IMT) circuit. The result is an efficient SI cancellation technique in the analog domain, which uses the circulator inherent SI signals.
    Type: Grant

  • Communicating data using backscatter modulation
    Patent number: 9774479
    Abstract: A system and method for full duplex wireless communication is disclosed. The system utilizes backscatter modulation of a first signal received by a guest device from a basestation to transmit a guest device message to a host basestation. The guest device utilizes the same antenna to both receive and transmit message signals.
