ABSTRACT:
A method of optimally distributing signal power for multiple users over a xDSL or wireless channel considers uses computationally efficient tools to achieve improved crosstalk avoidance. The method chooses between EQPSD and FDS signaling in a fashion that maximizes overall data rate. Rather than choosing EQPSD signaling in regions where there is low self-NEXT, but where the echo is high (relative to signal power), the method selects FDS signaling since the communication system acts in a manner similar to self-NEXT in such regions.
