The present invention provides methods and apparatuses for reducing near-far cross-talk interference between channels in a communication system. Channels of different lengths that are disposed adjacent to each other and carrying signals at the same frequencies often time create cross-talk interference in their neighboring channels. By spectrally shaping the signals carried on shorter lines the amount of cross-talk interference generated by these lines to longer lines may be significantly reduced, resulting in a better overall performance. In one embodiment of the present invention, a method of reducing the generation of near-far cross-talk interference includes spectrally shaping a signal carried on a first channel to reduce the amount of cross-talk coupling a neighboring second channel. In further embodiments, the shaping of the signal carried on the first channel is based in part on characteristics of the second and/or first channel. The characteristics include, but are not limited to, the length of the channels and the transfer functions of the channels. The present invention, in alternative embodiments, may also be embodied in a communication system, a central unit and a transceiver (or remote unit) or other suitable types of communication devices that are capable of shaping transmissions to reduce cross-talk interference generated by the transmissions.
