    摘要: A synchronization scheme for bidirectional data applications where the customer supplies data for transmission at a rate which is customer controlled. In accordance with the present invention, in each transmission direction, the customer data is converted into data symbols in a predetermined constellation. In response to these data symbols, additional symbols are added. In the disclosed embodiment, the additional symbols added are symbols lying outside of the constellation and are not used to represent customer data. The additional symbols added raise the symbol rate in each transmission direction to one higher than that provided by the symbols representative of the customer data alone. This higher symbol rate in each transmission direction is preferably the same, or the higher symbol rate in one direction is related to the higher symbol rate in the other direction by a rational number. At each receiver, the additional symbols are removed and customer data is recovered from its representative data symbols.

    摘要: To reduce near-end crosstalk (NEXT) in systems possessing excess bandwidth, a signal is transmitted from a first to a second location. At the second location, the received signal is examined and a characteristic of this signal is determined while the delay provided in the transmit signal path at this location is varied. Based on this examination, a particular amount of delay is introduced into the transmit signal path which reduces NEXT. This process is repeated for each direction of transmission. In the disclosed embodiment, the characteristic of the received signal which is determined is the mean square error and the amount of delay selected is that corresponding to the minimum mean square error.

    摘要: Advance training information is provided to a receiving Home network station via auxiliary coding, synchronized and/or included in the relevant Ethernet type packet. The advance training information may be, e.g., past equalizer, timing recovery circuit, AGC circuit, echo canceler values resulting from the reception of a previous frame. The training information may be, e.g., an early identity of the source of the packet, with a subsequent lookup performed by the receiving station for predetermined training value(s), or the training values themselves may be transmitted to the home network receiver via auxiliary coding. The auxiliary coding information may be transmitted before and/or during the frame training period of the relevant frame. This permits use of predetermined training values specific to the particular transmitter based on past frames received from that same transmitter during the training period for the received signal to be further refined from that determined from the auxiliary coding, resulting in more efficient and more accurate training of, e.g., a receiving equalizer, time recovery circuits, AGC, echo canceler, etc. Exemplary auxiliary coding techniques include, e.g., BPSK, FSK, QAM.
