| 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 |
