摘要： A system and method for optimizing the transmission of signals over a group of wires. In a preferred form of the present invention, a multi-wire bus connects a common card to a plurality of line cards. A framing protocol controls transmissions between the common card and the plurality of line cards. The framing protocol includes a frame having a prefix that identifies in which direction a given transmission will occur. The prefix also identifies over which wire or wires a given line card will receive data. Each of the line cards are configured to interpret the prefix so that at any given time data can be transmitted from the common card to one or more of the line cards by either transmission over a single wire or a plurality of wires.

摘要： A discrete multitone (DMT) receiver has a time domain equalizer (TDEQ) which is trained during initialization using an estimated channel impulse response (CIR). To eliminate wrap-around of the estimated CIR relative to the DMT frame alignment, and to remove leading zeroes, the estimated CIR is circularly advanced relative to the frame alignment for training the TDEQ. In subsequent communications of DMT symbols via the channel and the TDEQ, the equalized samples of the received DMT symbols are buffered to compensate, in a frame alignment of the received DMT symbols, for the advance of the estimated CIR in the initialization process and for a delay in the TDEQ.
