摘要： A XDSL line card including an allocator for allocating power to the multi-tone modulated communications on each of the subscriber lines, and for selecting control parameters sufficient to effect communications on each of the subscriber lines at a power level proximate to an allocated power level therefore. The line card also includes configurable components coupled to one another to form a transmit path and a receive path to couple to the digital subscriber lines. The configurable components are responsive to the control parameters selected by the allocator to initialize multi-tone communications over each of the plurality of subscriber lines at a power level proximate the allocated power level.

摘要： Adjusting a Modulation and Coding Scheme (MCS) or more generally, Layer One parameters, for a data packet based on packet information and priority is disclosed. The packet information can typically be extracted from the packet's header. Considering packet-specific information enables cross-layer optimization that can include consideration of packet error rate (PER) constraints, delay constraints, relative importance of packets within a data stream, beamforming (e.g., off or on, implicit or explicit—longer distances are more likely to merit implicit beamforming) constraints, and aggregation as a function of MCS or channel condition (more aggregation is generally desirable for higher MCS or better channels), to name several examples. It is also possible to differentiate drop probability based on the importance of frames like anchor frames, etc.

摘要： Disclosed are methods and apparatuses related to the routing of communications in a wireless mesh network so as to provide improved range, reliability and/or throughput. At least some aspects of the techniques and apparatuses can be implemented in an intermediary node (relay node) on a wireless mesh network. The relay node and other devices on the wireless network may implement a form of multiple-input multiple-output (MIMO) communication, such as multi-user MIMO (MU-MIMO). The devices on the network can communicate in accordance with IEEE standard 802.11.

摘要： A multi-tone modem with shared and discrete components forming a transmit path and a receive path configured to couple to a wired communication medium to communicate at least one multi-tone modulated communication channel thereon. The modem includes a multi-tone modulator component and a configurable frequency up converter component. The multi-tone modulator component is configured for multi-tone modulation and demodulation of a transmitted and received communication channel at a base band frequency range. The configurable frequency up converter component is coupled to the multi-tone modulator to selectably up convert the frequency range of the transmitted base band signal from the multi-tone modulator to that of a selected communication band and down convert received signals from the selected communication band to the base band for demodulation by the multi-tone modulator.

摘要： An apparatus for precoding multi-tone modulated transmissions of a plurality of communication channels over bundled subscriber lines. The apparatus includes a pseudo symbol controller and a precoder. The pseudo symbol controller detects a victim communication channel and an interferer communication channel having non-matching symbol rates, and transforms the interferor channel into a pseudo-symbol having both a substantially similar length as a corresponding symbol of the victim channel together with defined tonal characteristics expressed in terms of the interferor channel. The precoder assigns crosstalk coefficients to selected sub-channels or tones of the pseudo symbol and precodes the victim channel with the pseudo symbol using the crosstalk coefficients; thereby generating a precoded victim symbol which exhibits reduced crosstalk between the selected victim and interferor.

摘要： Networked modems configurable to establish a communication system on a wired communication medium. Each modem includes: a network module, transmit and receive path modules and a frequency domain echo canceller. The network module is configured to communicate with network modules of remaining ones of the at least three modems to allocate bandwidth of the shared communications medium for at least two discrete point-to-point communication links between corresponding pairs of the at least three modems. The transmit and receive path modules are configured for multi-tone modulation and demodulation of communications on the wired communication medium and are responsive to the bandwidth allocation of the network module to concurrently process at least a first discrete point-to-point communication link with a first modem among remaining ones of the at least three modems and at least a second discrete point-to-point communication link with a second among remaining ones of the at least three modems. The frequency domain echo canceller is configured to substantially cancel leakage of the communications transmitted on the transmit path into the receive path and to enable each point-to-point communication link to support full duplex communications.
