Abstract:
Systems and methods for resolving signal-to-noise ratio margin difference n dual latency discrete multi-tone (DMT)-based xDSL systems under colored noise conditions. Rather than assuming a constant power spectral density (PSD) for noise over fast and interleaved data paths of a dual latency system, band edges vulnerable to colored noise are determined and data on the fast data path is allocated away from these band edges. Also, receive windowing may be used to further enhance performance.
