Claim 0:
1. A system operative to replicate an exact frequency match among a plurality of output signals associated with spatial multiplexing, comprising:
a plurality of twisted pairs; and
a converter configured to receive a plurality of input signals, in which each of the plurality of input signals is an orthogonal frequency division multiplexing (OFDM) signal comprising a plurality of sub-carriers, and in which the plurality of input signals are associated respectively with a plurality of streams generated in conjunction with spatial multiplexing;
wherein the converter is further configured to:
obtain, via the plurality of twisted pairs, a reference signal associated with at least one original conversion signal, in which the at least one original conversion signal was used originally outside the converter to establish respective frequency ranges associated with the plurality of input signals;
utilize the reference signal to reproduce the at least one original conversion signal in a form of a respective at least one replica conversion signal; and
use the at least one replica conversion signal to respectively convert the plurality of input signals into the plurality of output signals, the plurality of output signals all occupying a same single frequency range, thereby causing the plurality of sub-carriers of any of the plurality of output signals to now exactly match in frequency a respective plurality of sub-carriers of any of the other output signals, thereby now enabling wireless transmission and successful decoding of the plurality of output signals, or a derivative thereof, in conjunction with the spatial multiplexing.
