| 20080285510 | Allocation of Signal-to-Noise Ratio margin in multi-carrier systems - Allocation of different signal-to-noise margins to different carriers in a multi-carrier system is described. A preferred embodiment comprises assigning signal-to-noise ratio (SNR) margins to carriers in a multi-carrier system, comprises assigning a first SNR margin to a first data service based upon a first service characteristic, assigning a second SNR margin to a second data service based upon a second service characteristic, transmitting data associated with the first data service using the first signal-to-noise margin, and transmitting data associated with the second data service using the second signal-to-noise margin. | 11-20-2008 |
| 20090190635 | TRANSCEIVER FOR COMMUNICATING OVER DIFFERENT MEDIA TYPES - One embodiment of the present invention relates to a transceiver. The transceiver includes a transmitter having a first transmission path configured to transmit a digital baseband signal over a wireline medium. In addition, the transmitter has a second transmission path configured to transmit a radio frequency signal over a wireless medium. Other systems and methods are also disclosed. | 07-30-2009 |
| 20100254380 | DSL Modem with Low-Power Mode - According to an embodiment, a DSL transceiver includes a power mode controller and a transmitter. The power mode controller is configured to set the DSL transceiver in a low power mode and move the DSL transceiver out of the low power mode responsive to the DSL transceiver receiving data. The transmitter is configured to transmit data only on a first group of sub-carriers when the power mode controller is moving the DSL transceiver out of the low power mode, the first group of sub-carriers being a subset of the sub-carriers available to the DSL transceiver for transmission. | 10-07-2010 |
| 20100254444 | Methods of Implementing Low-Power Mode for DSL Modems - According to an embodiment, a DSL transceiver is set in a low power mode and moved out of the low power mode responsive to the DSL transceiver receiving data. Data is transmitted only on a first group of sub-carriers when moving the DSL transceiver out of the low power mode, the first group of sub-carriers being a subset of the sub-carriers available to the DSL transceiver for transmission. | 10-07-2010 |
| 20110096870 | METHOD AND APPARATUS FOR VECTORED DATA TRANSMISSION - An apparatus includes a transmitter configured to transmit data via a plurality of communication channels of a communication connection. The transmitter is further configured to transmit a same sequence for vector training on each of the communication channels. The sequences for at least two of the communication channels are shifted with respect to each other. | 04-28-2011 |
| 20110110402 | ERROR REPORTING IN MULTI-CARRIER SIGNAL COMMUNICATION - In a communication device, a multi-carrier signal with at least one group of signal carriers is received from a communication connection. For each of the signal carriers, at least one individual error value is evaluated or generated. From the individual error values, a combined error value is evaluated or generated. The combined error value is transmitted on a backchannel of the communication connection. | 05-12-2011 |
| 20110294441 | POWER CONSUMPTION MANAGEMENT FOR MULTICARRIER ARRANGEMENTS - An arrangement for use in a telecommunication system includes a binder of subscriber lines, a local transceiver circuit, and a far-end crosstalk cancellation circuit. Each of the subscriber lines ends at one of a plurality of remote user terminals. The local transceiver circuit is associated with the binder of subscriber lines and comprises a plurality of substantially identical transceiver modules, each of the transceiver modules being associated to one or a small number of subscriber lines. The far-end crosstalk cancellation circuit is configured to reduce far-end crosstalk between the subscriber lines of the binder, and is operably connected to interface with at least parts of the received data of the respective local transceiver modules. The far-end crosstalk cancellation circuit operable to implement a blind training algorithm for at least one victim subscriber line based on signals received by the respective associated transceiver modules. | 12-01-2011 |
| 20120026926 | LOW POWER MODE FOR VECTORED DATA TRANSMISSION - Vectored communication devices and methods are provided for communication via a plurality of communication connections. Communication on at least some of the communication connections is switchable between a low power mode and a regular mode. | 02-02-2012 |
| 20120027069 | Protection of Communication Systems Against Repetitive Electrical Impulse Noise - A method limits the effect of repetitive electrical impulse noise in a communication system. The presence of the repetitive electrical impulse noise is detected during communication service. If the repetitive electrical impulse noise is detected, then a message is transmitted which signals that the repetitive electrical impulse noise is present. Other systems and methods are disclosed. | 02-02-2012 |
