Extremely high speed broadband access over copper pairs |
摘要 |
Disclosed is an apparatus that includes a plurality of parallel digital signal transmitters that each receive one of a plurality of digital sub-signals wherein each of the plurality of digital signal transmitters is configured to transmit one of the plurality of digital sub-signals that each have about the same bandwidth. The apparatus also includes a combiner coupled to the transmitters and configured to shift some of the plurality of digital sub-signals and to combine the plurality of shifted digital sub-signals into a combined digital signal that has a total bandwidth of that is approximately equal to the sum of the bandwidths of the plurality of digital sub-signals. The total bandwidth comprises a plurality of shifted bandwidths of the plurality of digital sub-signals at about the same offset with respect to each other. The combined digital signal is transmitted over a digital subscriber loop.
