1. A transmission device comprising:

  • a first receiver configured to receive an interfering signal via an antenna;

    a transmitter configured to generate first electromagnetic signals conveying first data;

    a coupler configured to generate first guided electromagnetic waves in response to combined electromagnetic signals, wherein the first guided electromagnetic waves propagate, without requiring an electrical return path, along a surface of a transmission medium of a distributed antenna system; and

    a cancellation circuit configured to generate the combined electromagnetic signals, based on the interfering signal and the first electromagnetic signals, wherein the combined electromagnetic signals mitigate interference by the interfering signal with the first guided electromagnetic waves.
