1. A method comprising:

  • modulating, by a first communication system, a first digital signal that encodes a first stream of data with a second digital signal that encodes a second stream of data that is different than the first stream of data, to generate a third digital signal that is adapted to occupy a first range of frequencies during wireless transmission by the first communication system,wherein the second digital signal encodes the second stream of data at a second frequency that is greater than a first frequency at which the first digital signal encodes the first stream of data;

    generating, by the first communication system, a filtered digital signal by removing or reducing a power level of frequency components of the third digital signal over a second range of frequencies that is to fall within the first range of frequencies during wireless transmission by the first communication system; and

    providing the filtered digital signal for wireless transmission by the first communication system.
