摘要：Systems and techniques to interpret signals on a noisy channel. A describedsystem includes a filter, buffer, detector, controller, and averager. The buffer can store agroup of signals, including a filtered digital signal and previous signal(s). The controller

can determine whether first discrete values are adequately indicated and initiate a retrymode when the first discrete values are not adequately indicated. The averager canproduce a new signal, in the retry mode, based on an average of at least a portion of thegroup of signals. The detector can interpret the new signal as second discrete values. Thecontroller can determine whether the second discrete values are adequately indicatedbased on a measurement of differences between hard decisions indicated by the newsignal and hard decisions indicated by the filtered digital signal. The controller canselectively exclude a signal of the group of signals from the average.
