  • Interference canceller tap sharing in a communications transceiver
    Patent number: 7738655
    Abstract: A novel mechanism for sharing filter taps across a plurality of interference cancellers. Each interference canceller may be directed to impairment, such as Ethernet impairments, including Ethernet 1000Base-T impairments. Various interference impairments include echo cancellation, NEXT cancellation and/or other interference detection or cancellation, etc. The hardware requirements of the interference impairment cancellers are reduced by sharing filter taps among the cancellers. In a first embodiment, the taps from a unified filter tap bank are shared across all the interference impairment cancellers for all four channels and over all ports. In a second embodiment, a portion of the taps of each filter are shared wherein each canceller comprises a fixed filter tap portion and a shared filter tap portion. A tap allocation algorithm assigns taps to those cancellers that need them the most. A canceller configuration is selected that yields maximal interference mitigation and the taps are allocated accordingly.
