Abstract: 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.

Abstract: The present invention relates to a crosstalk estimation device for estimating crosstalk between disturber communication lines and victim communication lines. The crosstalk estimation device is able to change the power spectral density PSD on the victim communication lines and/or the disturber communication lines. The crosstalk estimation device further receives measured changes in operational parameters on the victim communication lines and/or disturber communication lines in order to estimate the crosstalk induced in the victim communication lines and/or disturber communication lines.

Abstract: 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.

Abstract: The present invention relates to a wired transmission line testing method for determining at least one physical characteristic of a wired transmission line where the wired transmission line is coupled between a first line transceiver device and a second transceiver device. The wired transmission line testing method first comprises the steps of a first transceiver sending a first known excitation signal over the wired transmission line and subsequently the step of the first transceiver and the second transceiver both generating a first representation of a received signal respectively including reflected or forwarded portions of the known excitation signal and third a processing part deriving at least one physical characteristic of the wired transmission line based on the first representations generated by the first transceiver and the second transceiver. Furthermore, the wired transmission line testing method may comprise the additional steps of the second transceiver sending a second known excitation signal, then first transceiver and second transceiver both generating a second representation of a received signal respectively including forwarded or reflected portions of the second known excitation signal and the processing part deriving the at least one physical characteristic of the wired transmission line based on the first and second representations generated by the first transceiver and the second transceiver.
