  • Patent number: 8848505
    Abstract: A method for optimizing resource allocation for signal conditioning of DSL or other signal lines includes developing a signal quality metric using crosstalk interference and, optionally, signal to noise level. Use of existing pilot tone training selectively assigned to signal lines allows determination of the signal quality metric. A threshold level is selected and all signal lines having a signal quality metric above the threshold level are assigned crosstalk cancellation resources. Because the total number of signal lines requiring crosstalk cancellation is not known at the beginning, a particular threshold level may result in allocation of more than the available resources or allocation of significantly less than the available resources. When this happens the threshold level may be adjusted and the process repeated until crosstalk cancellation resources are assigned up to a usable limit.

The symbol boundary determination at the receiver can be performed in a time domain or a frequency domain manner. Another aspect pertains to an improved training sequence wherein pairs of identical symbols are transmitted by a transmitter. These symbols can be supplied to the transmitter in a time domain or a frequency domain manner.

  • Patent number: 8526513
    Abstract: The present invention discloses a method for transmitting data. In the embodiments of the present invention, whether to send blocking information used to block low priority data sent by an upper layer is determined through monitoring a delay of data during transmission, so as to prevent data overflow in a retransmission buffer of the sending end, thus achieving higher INP protection for the low priority data. Meanwhile, only the low priority data is blocked at this time, therefore, a sending end may further continue receiving high priority data, and mark the high priority data with a flag indicating retransmission is not needed when encapsulating the high priority data, so that a receiving end does not apply for retransmission of the high priority data when receiving the high priority data, thus ensuring the short delay requirement of the high priority data.

  • Patent number: 8520789
    Abstract: The present invention relates to the communication field and discloses a method and an apparatus for implementing pulse synchronization, so that the control on a single-chip multi-channel device can be simplified. A method for implementing pulse synchronization includes: when a cycle count value corresponding to a reference symbol port of the multiple ports reaches a length of a predetermined pulse cycle, obtaining, by a microprocessor, cycle count values corresponding to the multiple ports; obtaining lengths of temporary synchronization cycles of the multiple ports according to the length of the predetermined pulse cycle and the cycle count values corresponding to the multiple ports; and sending the lengths of the temporary synchronization cycles to logic circuits corresponding to the multiple ports. Embodiments of the present invention are mainly applied in communication systems to output pulse symbols synchronously.

  • Patent number: 8175262
    Abstract: A system for processing subscriber line data signals uses a coprocessor to receive signals in a pre-determined order from a plurality of line interface cards. The coprocessor uses the pre-determined order to sort the data signals by tone and process all received signals on the same tone at the same time. Because all signals on a tone, or those on a tone with known crosstalk issues, are processed together, the signal improvement is better than prior art methods. When not used, the coprocessor may be replaced with a loop-back circuit to reduce cost when crosstalk is not a significant issue.

  • Patent number: 7996453
    Abstract: FFT butterfly data sets may be stored in memory in a predetermined order. Such an order may allow a butterfly data set to be read from a single memory address location. The memory addressed may be computed by an address rotary function depending on the butterfly and stage of the FFT. Addressing the memory in such a manner may allow each butterfly data set of a subsequent FFT stage to be stored to a single memory location. Shuffle registers may delay the writing of FFT butterfly results to the memory until most of the data corresponding to a particular butterfly operation has been computed. The shuffle registers may rearrange and combine the results of one or more butterfly operations in a different manner from which they have been computed. Combining the results in this manner may allow a subsequent FFT stage to access data by addressing a single memory location.

  • Patent number: 7801233
    Abstract: Improved techniques for concurrent channel equalization and far-end crosstalk channel compensation (e.g., estimation and/or cancellation) in a multicarrier data transmission system are disclosed. The improved techniques can produce coefficients for an electronic fitter that provide channel equalization and for an electronic filter that provides cancellation of the far-end crosstalk. These coefficients can be initially trained and then subsequently updated during data transmission. Optionally, common coefficient determination resources can be utilized for both far-end crosstalk and near-end crosstalk purposes. These improved techniques are particularly suitable for use with a digital multicarrier communication system having multiple-input multiple-output systems.

  • Patent number: 7697619
    Abstract: An improved training sequence for estimating a channel (e.g., channel impulse response) in the time domain is disclosed. The improved training sequence enables time-domain estimation and eliminates the need for correct frequency-domain channel estimation at every frequency. By utilizing the training sequence according to the invention, estimation of each of a plurality of time-domain channel taps can be decoupled from each other. This enables a channel estimate to be performed with not only a higher convergence speed but also lower complexity.
