20140112380 | ALIEN INTERFERENCE REMOVAL IN VECTORED DSL - A vectored DSL system reduces or eliminates correlated alien interference in active DSL lines in the vectored system by collecting pseudo signals from inactive lines that do not carry upstream DSL transmissions and/or from common-mode voltage signals from active lines. The collected pseudo signals contain in-domain interference, such as FEXT interference from the active DSL lines in the vectored system, and correlated alien interference. After removing the in-domain interference from the pseudo signals, the remaining alien interference data can be used to generate FEXT cancellation coefficients or the like that are used in DSL vectoring to remove the correlated alien interference from upstream DSL user signals from the active DSL lines. The generated FEXT cancellation coefficients are used in a manner analogous to in-domain FEXT data collected from the active lines during training, tracking, etc. | 2014-04-24 |
20140112381 | DM-CM DIVERSITY RECEIVER FOR A WIRELINE COMMUNICATION SYSTEM - In general, the present invention provides methods and apparatuses for exploiting the extra degree of freedom provided by the sensing of the CM signal along with the DM signal at the receiver end of a wireline communication system. According to certain aspects, this extra degree of freedom can be used to cancel alien noises at the receiver in both upstream downstream directions. According to further aspects, a CM channel can be potentially used to exploit the diversity created in the CM channel along with the regular DM channel. This acts as the motivation for employing a diversity receiver scheme at the receiver, especially in downstream communications received at a Customer Premises. | 2014-04-24 |
20140112382 | Systems for High-Speed Backplane Applications Using Pre-Coding - In conventional Backplane Ethernet systems, data is transmitted over two pairs of copper traces in one direction using a PAM-2 scheme and a baud rate of 10.3125 GHz, giving an effective bit rate of 10.3125 Gbps. The rate at which data can be transmitted in Backplane Ethernet systems, while still being reliably received, is typically limited by ISI caused by the dispersive nature of the copper traces, frequency dependent transmission losses caused primarily by skin effect and dielectric loss of the copper traces, and cross-talk from adjacent communication lines. The present invention is directed to systems for overcoming these and other signal impairments to achieve speeds up to, and beyond, twice the conventional 10 Gbps limit associated with Backplane Ethernet systems. | 2014-04-24 |
20140112383 | DECODING VIDEO STREAMS USING DECODERS SUPPORTING A DIFFERENT ENCODING PROFILE - In various embodiments, video streams are decoded using decoders that support a different decoding profile. First processing circuitry is configured to receive a video stream encoded using a first encoding profile, transcode the video stream from the first encoding profile to a second encoding profile, and store the transcoded video stream in an output buffer. Second processing circuitry is configured to receive the transcoded video stream from the output buffer and decode the transcoded video stream according to the second encoding profile. The second processing circuitry may be unable to decode the video stream encoded using the first encoding profile. | 2014-04-24 |
