摘要： A method for transmitting data packets of at least two different priority levels via one or more bearer channels is described. The method comprises the steps of fragmenting a data packet into a plurality of corresponding code words, each code word comprising a sync code, with the sync code being adapted for indicating a priority level of the corresponding data packet, and of transmitting the code words via the one or more bearer channels. In case high priority code words corresponding to a high priority data packet arrive during transmission of low priority code words corresponding to a low priority data packet, the following steps are performed: interrupting transmission of low priority code words, transmitting the high priority code words corresponding to the high priority data packet, and resuming the transmission of the low priority code words via the one or more bearer channels.

摘要： A DSL transmitter and receiver are disclosed that efficiently estimate crosstalk interference. When transmitting over a DSL cable, each of the lines of the cable cause interference in the signals traveling though the other lines in the form of crosstalk. In order to reduce the complexity of the crosstalk estimation calculations, the transmitter sends a measurement signal whose matrix includes a plurality of sub-matrices that include less than all of the signal slots and are modulated with QAM +1s or −1s. Meanwhile, the remaining signal slots are modified with QAM 0 s, which do not require any processing during the crosstalk estimation. Rather than calculating crosstalk vectors of all lines, the receiver need only calculate the crosstalk vectors for the signal slots contained within the sub-matrices, thereby significantly reducing complexity.

摘要： An upstream signal power in a communication system is optimized. At least one system parameter is determined and a bits and gains table is modified. For example, a maximum received power parameter for the transmitting device is used by the receiving device to calculate a power backoff parameter. The power backoff parameter is used to calculate the bits and gains table which is then used by the transmitting device. The new SNR may be estimated. This estimation may distinguish between noise sources that vary with the signal level received and those that do not.

摘要： To determine the channel characteristic of a channel (CHANNEL) between a transmitter (TX) and a receiver (RX), a predetermined periodic signal of pulse amplitude modulated symbols is modulated on waveforms by a cosine modulated filter bank (DWMT MOD) in the transmitter (TX), and the waveforms are transmitted over the channel (CHANNEL). In the receiver (RX), the received pulse amplitude modulated symbols are demodulated from the waveforms by a cosine modulated filter bank (DWMT DEMOD), pairs of the received pulse amplitude modulated symbols are combined to form received quadrature amplitude modulated symbols, and the received quadrature amplitude modulated symbols are divided by the transmitted predetermined pulse amplitude modulated symbols considered pairwise as transmit quadrature amplitude modulated symbols. So, samples of the channel characteristic are generated.

摘要： In a multi-carrier communication system wherein data are transferred bi-directionally in a time division duplexed way, a first pilot carrier is used to transfer a sample rate between two transceivers (VDSL_LT, VDSL_NT) and a second pilot carrier is used to transfer a time division duplexing frame rate between the two transceivers (VDSL_LT, VDSL_NT). The first pilot carrier has an instantaneous frequency that is a fraction of the sample rate of the first transceiver (VDSL_LT) and is orthogonal to other carriers used in the multi-carrier communication system. The second pilot carrier has a mean frequency that is a fraction of the time division duplexing frame rate and is also orthogonal to the other carriers used in the multi-carrier communication system. The second pilot carrier is different from the first pilot carrier.

摘要： In a multi-carrier transmission system, a clock timing error (&tgr;e) is calculated at the receiver's side and used for synchronization between a transmitting modem and a receiving modem (RX1). The clock timing error (&tgr;e) is calculated from phase errors (&phgr;0, &phgr;1, . . . , &phgr;i, . . . , &phgr;N-1) detected for a plurality of pilot carriers during a tracking mode in such a way that the share (Ai) of a phase error (&phgr;i) detected for a particular pilot carrier in the clock timing error (&tgr;e) depends on the transmission quality (SNRi) of that pilot carrier over the transmission medium in between the two modems. In this way, the robustness of the synchronization for narrowband noise near a pilot carrier is improved significantly.
