In a full-duplex communication device, the receiver will generally experience significant self-interference from the full-duplex communication device's own transmitter transmitting a strong outbound signal over the same channel that the receiver is to receive a weak inbound signal. The apparatus and method are configured to adjust a phase and gain of the outbound signal provided at the output of a power amplifier (PA) and inject the phase and gain adjusted outbound signal at the input of a low-noise amplifier (LNA) to cancel the interference from the outbound signal in the inbound signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Self-interference cancellation for full-duplex communication using a phase and gain adjusted transmit signal","description":"The present disclosure is directed to an apparatus and method for cancelling self-interference caused by full-duplex communication.
