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.

Abstract: Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include supplemental information. The supplemental information may be associated with one or more symbols of the preamble. The supplemental information may contain predetermined header information for use by nodes operating on the communication network medium.

The method includes measuring a respective signal-to-noise-ratio (SNR) margin for each respective tone in a multicarrier channel. A plurality of tone groups is determined by, for each tone group, grouping at least one tone with a relatively high SNR margin with at least one tone with a relatively low SNR margin to form a tone group. Ordering information describing the plurality of tone groups is communicated to a transmitter. The transmitter is configured to load bits for transmission by way of the tones based at least on the ordering information.

Abstract: Described herein are techniques related to data communications using a data packet having at least one frame with a robust preamble for use over media having a high degree of non-stationary noise (e.g., impulsive noise). The described techniques employ a preamble with a structure having multiple transitions between the preamble sections. Each transition indicates the start of the upcoming frame. With the techniques described herein, if noise damages the transitions between such sections beyond recognition, the receiver can still determine the frame start time from the one or more of the undamaged transitions. Thus, the robustness of communications via the noisy media is significantly increased. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
