20140119419 | Channel Estimation - Methods and devices related to channel estimation for a communication system comprising a plurality of communication connections are provided. For channel estimation, test sequences are used having three different elements, for example −1, 0 and +1. | 05-01-2014 |
20140119536 | Spectrum Management - Various methods, techniques and devices are disclosed which optimize an output power spectral density taking properties and changes of crosstalk reduction like crosstalk precompensation into account. The techniques disclosed may for example be employed in distribution points of a communication system. | 05-01-2014 |
20150124943 | Performance Monitoring for Discontinuous Operation Modes - Methods and apparatuses are provided wherein performance of lines configured for discontinuous operation is monitored on symbols transmitted using a base configuration in which the lines are active. On the basis of the monitored performance, performance may be calculated for other configurations in which one or more of the lines are discontinued. | 05-07-2015 |
20160073448 | Timesharing for Low Power Modes - Techniques for implementing timesharing in discontinuous systems, for example to implement low power modes, are discussed. In some embodiments, a set of bit loading tables is determined in advance, and bit loading tables are then selected based on which lines are transmitting and which are quiet. | 03-10-2016 |
20160087677 | Low Power Modes for Data Transmission from a Distribution Point - Methods and devices are discussed where a common bit loading table is constructed from minimum gain from a plurality of bit loading tables for different combinations of lines being in a transmit or quiet mode. | 03-24-2016 |
20160119025 | Methods, devices and systems of supporting discontinuous operation in communication systems using vectoring - Methods, devices and systems of supporting discontinuous operation in communication systems using vectoring Methods, devices and techniques are disclosed where vectoring is adapted to lines becoming inactive and active, for example in a discontinued operation. In some embodiments, the vectoring is modified based on already present coefficients. | 04-28-2016 |
20160119026 | Communication Coexistence in Overlap Spectrum - Communication in a first spectrum and via a first transmission line of first data is according to a time-division duplexing scheme such as G.fast. Communication in a second spectrum and via a second transmission line of second data is according to a frequency-division duplexing scheme such as VDSL2. The first and second spectra both comprise an overlap spectrum. The first transmission line experiences first crosstalk from the second transmission line and the second transmission line experiences second crosstalk from the first transmission line. | 04-28-2016 |
20160119107 | Special operations channel in vectored systems - Methods and devices are provided wherein a signal sent on a special operation channel is modified by an identification of a line. | 04-28-2016 |
