Claim Text:
1. A method comprising: generating, by a base station communication system, a digital signal that is adapted to occupy a first range of frequencies during a wireless transmission by the base station communication system, wherein the digital signal is generated by modulating an input digital signal with another digital signal that encodes a stream of data at a frequency that is greater than a frequency at which the input digital signal encodes a different stream of data, the stream of data encoded by the input digital signal having been designated for transmission to a particular receiving device in a cellular communication system; generating a filtered digital signal by removing or reducing a power level of frequency components of the digital signal over a second range of frequencies that is to fall within the first range of frequencies during the wireless transmission by the base station communication system; and providing the filtered digital signal for the wireless transmission by the base station communication system.
