Abstract
Disclosed are methods and associated devices for minimizing the undesirable affects of interference signals in the upstream spectrum of an multiuser interactive system. The method comprises receiving an initial upstream signal at a multiuser interactive processor in a multiuser interactive system. The frequency of the initial upstream signal is at a frequency within the upstream spectrum. Next, the multiuser interactive processor determines a measure of interference associated with at least a portion of the upstream spectrum. Based upon the measure of interference, an upstream channel, from within the upstream spectrum, is selected. The upstream channel is within the upstream spectrum. Finally, the multiuser interactive processor transmits a second signal representative of the upstream channel.
