  • Systems and methods for resolving signal-to-noise ratio margin difference in dual latency discrete multi-tone-based xDSL systems under colored noise conditions
    Patent number: 7907658
    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.

  • Reduced complexity time-frequency trained equalizer for discrete multi-tone based DSL systems
    Patent number: 7212595
    Abstract: The present invention provides a system and method for implementing a new TEQ training approach that trains TEQ coefficients by exploiting both time-domain and frequency-domain information. An advantage of this technique is that it reduces memory usage due to the training process. In addition, the complexity of the training process is simplified, and the associated computational work is reduced. The reduction of memory usage and computational work in turn may lead to cost savings, power consumption savings and other advantages.
