Method and system for tunable upstream bandwidth utilizing an integrated multiplexing device

Abstract

Methods and systems are provided for use of tunable bandwidths. An example system may comprises a plurality of filters, with each of filters being configured for filtering signals corresponding to a particular frequency band associated with a particular stream. One or more adjustments may be determined and applied to one or more of the plurality of filters. The adjustments may comprise modifications to at least one frequency band associated with at least one of the plurality of filters. Leakage affecting the plurality of filters may be measured or estimated, and a compensation adjustment applicable to particular transmitted and/or received signals may be determined based on measured or estimated leakage. The leakage may be estimated based on analysis of digital baseband signals corresponding to transmitted and/or received signals.
