摘要： Systems and method for minimum power leakage windowing for VDSL using least squares technique are provided. A coefficient vector is defined for the first N samples. The window is then defined in terms of this coefficient vector. The leakage power of the Kth tone is defined in terms of the window. A least squares minimization is performed on the leakage power to determine the optimal value of x. The window is implemented using this value of x, thereby reducing the power leakage in the out-of-band and RFI band regions in the frequency domain.

摘要： The present invention provides for a method and system to implement time-domain equalizer (TEQ) training to shorten the channel impulse response of twisted copper lines for DMT-based VDSL systems. The coefficients of TEQ are trained when training signal has cyclic extension (CE), such as specified in current VDSL standard and proposed for VDSL2. The invention effects frame alignment and removal of CE to effectively permit implementation of TEQ training for VDSL where the training signal has cyclic extension. The advantage of this new invent is that Intersymbol interference (ISI) can be reduced in the current VDSL systems and FFT (Fast Fourier Transform) can be applied in place of presently used DFT (Direct Fourier Transform) for TEQ training. Use of the present invention in effectively implementing TEQ training in systems having cyclic extension results in reduced complexity, power saving, reduced memory requirements in terms of code space, and cost savings

摘要： 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.
