ABSTRACT:
An apparatus and method of transmitting digital data over a coaxial cable a noisy environment using several carriers with narrower bandwidths in place of the single carrier with a wide bandwidth. In a frequency spectrum, these several carriers are located between interfering harmonic and spurious noise frequencies generated by the other signals, an particularly clock signals. These narrow signals are then combined for transmission over a cable, substantially reducing noise in the signal recovered at the receiving end.
