1. A method comprising:

  • in a full duplex transceiver, generating an interference-reduced signal by combining an analog self-interference cancellation signal to an incoming signal that includes a desired signal and a self-interference signal, wherein the analog self-interference cancellation signal destructively adds to the self-interference signal to create a residual self-interference signal;

    processing the interference-reduced signal to further reduce the residual self-interference signal using a baseband residual self-interference channel estimate.
