Patent ID: 8218610

Claim:
A method, in a first transceiver that uses a plurality of carrier signals for receiving a bit stream that was transmitted by a second transceiver, wherein each carrier signal has a phase characteristic associated with the bit stream, the method comprising: receiving the bit stream from the second transceiver, wherein: each carrier signal is associated with a value determined independently of any bit value of the bit stream carried by that respective carrier signal, the value associated with each carrier signal determined by a pseudo-random number generator, a phase shift for each carrier signal is at least based on: the value associated with that carrier signal, and the combining of a phase for each carrier signal with the phase characteristic of that respective carrier signal so as to substantially scramble the phase characteristics of the plurality of carrier signals, and multiple carrier signals corresponding to the plurality of phase shifted and scrambled carrier signals are used by the first transceiver to demodulate a same bit value of the received bit stream; and wherein: the first and second transceivers communicate over one or more of a pair of twisted wires of a telephone subscriber line and fiber optic, and the first and second transceivers transport video.
