    • In one embodiment, a receiver has a reference generator and a main equalizer. The reference generator equalizes a received signal using one or more pilot reference signals. Then, the reference generator decodes one or more predetermined data channels of the equalized signal, makes hard decisions on the data of each decoded channel, and regenerates the original coding sequence of each decoded channel. The main equalizer uses each re-encoded channel as an additional reference signal along with one or more pilot signals to equalize a time-delayed version of the received signal. In alternative embodiments, the receiver might also have a step-size generator which selects optimum step sizes from a look-up table based on the number of re-encoded channels and the power of those channels. The step size is then used by the main equalizer along with the re-encoded channels to equalize the time-delayed received signal.
    • 在一个实施例中,接收器具有参考发生器和主均衡器。 参考发生器使用一个或多个导频参考信号来均衡接收信号。 然后,基准发生器解码均衡信号的一个或多个预定数据信道,对每个解码信道的数据作出硬判决,并重新生成每个解码信道的原始编码序列。 主均衡器使用每个重编码信道作为附加参考信号以及一个或多个导频信号来均衡接收信号的时间延迟版本。 在替代实施例中,接收机还可以具有步长生成器,其基于重新编码的信道的数量和这些信道的功率从查找表中选择最佳步长。 然后,主均衡器与重新编码的信道一起使用步长来均衡时间延迟的接收信号。
