摘要： An improved multi-channel receiver for satellite broadcast applications or the like. In an exemplary embodiment, the receiver has an adaptive equalizer configurable to operate with QPSK or 8PSK modulated signals. In the equalizer, a slicer table memory responsive to an 8-level quantizer (slicer) and a select signal is configured to map the output of the quantizer into QPSK or 8PSK symbol coordinates depending on whether the QPSK or the 8PSK signal is being received. The slicer table memory may be loaded with the symbol coordinates calculated from data in the 8PSK signal. A pattern matcher determines if the 8PSK or the QPSK signal is being received and asserts the select signal to configure the slicer table memory accordingly.

摘要： Analog modems are enabled to better learn the slicing levels employed at the interface to a digital transmission network by reducing the effects of the various noise sources. Initially a training sequence is received to preliminarily adjust the analog modem's equalizer. Thereafter, a special training sequence, protected against intersymbol interference, is employed to collect samples of each slicing level, to ascertain the least mean squared value of each slicing level from the received samples and to obtain the channel's impulse response at each slicing level. To mitigate the effects of robbed bit signaling that may be employed in the digital transmission network, an array of slicers is provided to determine which bit position is being robbed and to base level learning on samples obtained from the non-robbed positions.

Depending on the means squared error (MSE) between the input and the output of the slicer, the slicer tables continue to be updated, and the feed-forward and feed-backward equalizer filters are selectively adjusted in accordance with the channel impulse response ascertained at each of the slicing levels.

摘要： A general, low cost method for detecting and compensating any non-linear digital impairment and linear analog gain for data communication systems transmitting signals through telephone networks is disclosed. The inventive method eliminates the need of costly digital impairment tables any &mgr;-law encoders/decoders. Before each data transmission session, non-linear digital impairment and linear analog impairment is computed and then compensations for the digital and analog impairments are performed. Thereon, the actual data transmission begin. The digital impairment and analog impairment values must be computed for each data transmission session, but the values remain constant for the entirety of a session.

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.
摘要翻译：通过辅助编码向接收家庭网络站提供预先训练信息，同步和/或包括在相关的以太网类型分组中。预先训练信息可以是例如过去均衡器，定时恢复电路，AGC电路，由接收前一帧产生的回波消除器值。培训信息可以是例如分组的源的早期身份，接收站对于预定训练值执行的后续查找，或者训练值本身可以经由辅助方式发送到家庭网络接收机编码。辅助编码信息可以在相关帧的帧训练周期之前和/或期间传送。这允许在训练期间基于从相同发射机接收的过去帧来使用特定发射机的预定训练值，以便从辅助编码确定的接收信号进一步改进接收信号，导致更有效和更准确的训练例如接收均衡器，时间恢复电路，AGC，回波消除器等。示例性辅助编码技术包括例如BPSK，FSK，QAM。
