摘要:
A DSL or other communication system includes a modem or other communication device having at least one antenna that is configured to collect interference data relating to interference noise affecting communication signals being received by the communication device. The interference may include RF interference, such as AM radio interference, crosstalk and other types of interference from various sources. The interference data collected by the antenna is used by an interference canceller to remove and/or cancel some or all of the interference affecting received signals. In some embodiments of the present invention, more than one antenna may be used, wherein each antenna can collect interference data pertaining to a single source of interference noise. Where a modem or other communication device is coupled to multiple telephone lines, only one of which is being used as the active DSL line, wires in the remaining telephone lines or loops can be used as antennas. Moreover, the antenna may be an antenna, per se, such as a compact AM radio antenna or any other suitable structure or device for collecting the type(s) of interference affecting signals received by the communication device.
