    • A system for adaptively updating precoder taps comprises a first signal path, a second signal path, a delay mechanism, and logic. The first signal path is configured to receive encoded signals. The first signal path has a decoder that is configured to decode the encoded signals thereby recovering data originally transmitted from a remote transmitter. The delay mechanism is configured to receive and delay the encoded signals. The second signal path is connected in parallel with the first signal path and is configured to receive the encoded signals delayed by the delay mechanism. The second signal path has an adaptive filter configured to filter the encoded signals received by the second signal path based on a set of coefficients of the adaptive filter. The adaptive filter is configured to adaptively update the coefficients based on the data recovered by the first signal path. The logic is configured to adaptively generate new precoder taps based on the coefficients and to transmit the new precoder taps to a precoder.
    • 用于自适应地更新预编码器抽头的系统包括第一信号路径,第二信号路径,延迟机制和逻辑。 第一信号路径被配置为接收编码信号。 第一信号路径具有解码器,其被配置为对编码的信号进行解码,从而恢复最初从远程发射机发送的数据。 延迟机构被配置为接收和延迟编码的信号。 第二信号路径与第一信号路径并联连接,并被配置为接收延迟机制延迟的编码信号。 第二信号路径具有自适应滤波器,其被配置为基于自适应滤波器的一组系数来对由第二信号路径接收的编码信号进行滤波。 自适应滤波器被配置为基于由第一信号路径恢复的数据自适应地更新系数。 逻辑被配置为基于系数自适应地生成新的预编码器抽头,并将新的预编码器抽头发送到预编码器。

    • A frame sync acquisition mechanism accurately locates a frame synchronization word within successive selectively bit-stuffed frames of data by not only looking for the frame sync word in the two expected alternative frame sync word locations based upon either the addition of stuff bits or the lack of such stuff bits, but also selectively examining a pair of additional potential locations, one of which precedes and the other of which succeeds the two expected alternative frame sync word locations. If an exact match with the frame sync word is located in either of the expected locations, that location is selected as the reference for the next succeeding frame. During the search of the next successive frame and for every succeeding frame, an attempt is made to initially match the frame sync word with in either of these expected locations. If unable to do so, the search is expanded to encompass the entire window of location uncertainty, so as to include the two additional locations. During this expanded search, that location which yields the smallest number of bit errors is declared as the reference location for the next succeeding frame. If there is a failure to find an exact match over the course of a plurality of successive frames, an out-of-sync condition is declared, and the frame sync acquisition of mechanism is re-initialized.
    • 帧同步获取机制通过不仅在两个预期的备选帧同步字位置中寻找帧同步字,而是基于填充位的添加或缺少 这样的填充位,而且还选择性地检查一对附加的潜在位置,其中一个位于两个预期的替代帧同步字位置之前和另一个之后。 如果与帧同步字的精确匹配位于预期位置中的任意一个位置,则选择该位置作为下一个后续帧的参考。 在搜索下一个连续的帧期间,并且对于每个后续的帧,尝试使帧同步字与这些预期位置中的任一个初始匹配。 如果不能这样做,搜索扩展到包含整个位置不确定性窗口,以便包括两个附加位置。 在这个扩展搜索期间,产生最小数量位错误的位置被声明为下一个后续帧的参考位置。 如果在多个连续帧的过程中找不到精确匹配的失败,则声明不同步状态,并重新初始化机制的帧同步获取。
