摘要： A power control method for transceiver units conveying data over discrete tones. The method includes the steps of: determining a transmit power over a physical channel for each individual tone, such that this transmit power maximizes a weighted function of data rates achievable with this tone over the physical channel and over modeled neighboring channels, with the constraint that this transmit power conforms to a transmit power mask, summing up the data rates over the whole set of tones, adjusting the weights such that the total data rates over the modeled neighboring channels reach some target data rates, and such that the total data rate over the physical channel is maximized, with the constraint that each weight is identical over the whole set of tones.

摘要： A method for determining transmission characteristics over a first communication path and a second communication path, while an amount of the signal transmitted over the first communication path couples into the second communication path. In case of excess of capacity over the first communication path and a shortage of capacity over the second communication path, the transmit power over said first communication path is decreased such that the requested service is met over both communication paths. This optimal transmit power can be determined by trying successive transmit power values until the requested service is met, e.g. by means of a dichotomy algorithm or the like. The optimal transmit power value can be computed directly as well, e.g. by making use of the transfer characteristics of the coupling path. A transceiver unit may also be used to implement the present method.

摘要： A transmitter device (210) and associated receiver device (211) providing a retransmission scheme for use in communications involving lossy media. The transmitter device (210) receives data packets (201) from a source and adds protection to selected subflows before delivering (203, 206) them to the receiver device (211). The receiver device (211) is able to remove the protection and process (207) the data packets further. The retransmission scheme introduces greater reliability on the lossy medium by restricting the retransmission (208, 209) to a particular link and to selected subflows of traffic in the connection between a source and a destination.

摘要： The present invention relates to a method for data-flow quality control in a Digital Subscriber Line communications system comprising a transmitter, a receiver, and a Digital Subscriber Line intercoupling the transmitter and the receiver. The transmitter sends a data-flow to the receiver, where the data-flow is modulated onto data-carriers according to a bit allocation indicative for the number of bits to be modulated on each data-carrier. The method comprises the steps of the receiver measuring the data-flow quality and subsequently the receiver instructs the transmitter to decrease the bit allocation with a same amount for a plurality of data-carriers in case the data-flow quality is unsatisfactorily low. Then the transmitter decreases the bit allocation accordingly.

摘要： A method involves performing a plurality of acts. The acts include transmitting a first signal stream to a first channel of a multi-channel communications medium while transmitting a second signal stream to a different second channel of the medium. The second signal stream is substantially temporally correlated to the first signal stream. The method includes receiving an SINR measured at a receiver configured to receive signals from the first channel. The SINR is measured while the receiver received the first signal stream. The method includes determining a channel matrix element between the first and second channels or a ratio of said channel matrix element to a diagonal element of the channel matrix. The act of determining is based on the received SINR.
