Patent ID: 8553791

Claim:
A method for transmitting a data stream simultaneously over discontiguous channels of wireless spectrum, the method comprising: generating, by a transmission system, a first digital data signal by combining an input digital data signal with another digital data signal that encodes a stream of data at a frequency that is higher than a frequency at which the input digital data signal encodes a different stream of data, the stream of data encoded by the input digital data signal having been designated for transmission to a single receiving device in a cellular communication system; converting, by a digital signal processing apparatus of the transmission system, a second digital data signal that encodes the first digital data signal from a time domain to a frequency domain, so as to create a representation of the second digital data signal in the frequency domain that encodes the input digital data signal across a frequency band of a plurality of radio frequency channels that have been designated by a government governing body or an international agreement; filtering, by the digital signal processing apparatus of the transmission system, the representation of the second digital data signal in the frequency domain to reduce, from the representation of the second digital data signal in the frequency domain, a power level of at least two discontiguous channels of the frequency band that correspond to channels of the frequency band that have been identified as occupied by transmissions from one or more third-party transmission systems that are not transmitting devices in the cellular communication system, so as to generate a filtered representation of the second digital data signal that encodes the input digital data signal across at least three discontiguous channels of the frequency band; converting, by the digital signal processing apparatus of the transmission system, the filtered representation of the second digital data signal from the frequency domain the time domain, so as to generate a third digital data signal; converting, by the transmission system, a fourth digital data signal that encodes the third digital data signal to a first analog signal that encodes the input digital data signal across the at least three discontiguous channels of the frequency band; filtering, by the transmission system, a second analog signal that encodes the first analog signal to reduce, from the second analog signal, a power level of portions of the second analog signal that are outside of the frequency band, so as to generate a third analog signal, without use of channel hopping or channel bonding; translating, by the transmission system, the second analog signal or the third analog signal to a higher frequency range; and wirelessly transmitting, by the transmission system and over the frequency band at the higher frequency range, a fourth analog signal that encodes the third analog signal.
