METHOD AND APPARATUS FOR OPTIMIZING DYNAMIC RANGE IN DMT MODEMS |
摘要 |
<p>A digital subscriber line XDSL communication system for optimizing dynamic range in digital multi-tone modulated (DMT) modems. The system comprises a digital subscriber line access multiplexer (DSLAM) and at least one modem. The DSLAM distributes a near end crosstalk (NEXT) model of anticipated disturbance from neighboring disturber subscriber lines. The at least one modem has a transmit path and a receive path. The at least one modem couples to the DSLAM and is responsive to the distributed NEXT model to adjust a dynamic range of an analog portion of the receive path to accommodate the anticipated disturbance modeled in the distributed NEXT model.</p> |
