    摘要： The invention relates to the field of equalizer technology, more specifically, to a signal decision device and a signal decision method. By calculating an error for the hard decision signal, and then implementing a condition decision via the threshold condition, the invention decides to output the equalization time domain signal or the hard decision signal, and reduces the error of the output signal. The above technical solution improves the performance of the equalizer by implementing the iteratively update directly via soft bit information instead of the hard decision signal.

    摘要： A slicer can receive a communication signal having a level or amplitude that is between two discrete levels of a multilevel digital communication scheme. The slicer can compare the communication signal to a plurality of references such that multiple comparisons proceed essentially in parallel. A summation node can add the results of the comparisons to provide an output signal set to one of the discrete levels. The slicer can process the communication signal and provide the output signal on a symbol-by-symbol basis. A decision feedback equalizer (“DFE”) can comprise the slicer. A feedback circuit of the DFE can delay and scale the output signal and apply the delayed and scaled signal to the communication signal to reduce intersymbol interference (“ISI”).

    摘要： A method and apparatus for receiving a stream of data values from a data medium, wherein the received data values correspond to ideal values but may include added noise that is dependent on previous noise and dependent on data on the data medium, said ideal values being determined by possible values of data on the medium, and for outputting information specifying a sequence of states corresponding to the stream of received data values, said sequence of states corresponding to possible data values on the medium, the apparatus comprising: a first detector, for calculating state sequence likelihood information based on a first noise model and received data values, and for providing said state sequence likelihood information to a second detector; a second detector for calculating weighting values indicating likelihoods that a data value received at a particular time corresponds to a particular state transition, using a second noise model, received data values, and state sequence likelihood information from the first detector; a traceback unit for determining a most likely sequence of data values using said calculated weighting values; and an output for outputting information specifying said determined sequence of states.
