Abstract: Data symbols in an input signal are detected with a slicer of a DFE of a transceiver device. An output of a feedback filter of the DFE is generated, during a particular clock cycle, based on a first set of one or more data symbols detected during first one or more previous clock cycles and a second set of one or more data symbols detected during second one or more previous clock cycles. The second set is separated from the first set by a third set of one or more data symbols detected during third one or more clock cycles that occur after the first one or more clock cycles and before the second one or more clock cycles, where the output is generated without use of the third set of symbols. The output is subtracted from the input signal to generate an equalized input to the slicer.

Abstract: Provided are a formulation which creates protection layers on the metal friction and wear surface and a method for preparing the same. The formulation provided here comprises 45-99 parts laminar hydroxyl silicate powders, 1-50 parts formulation which creates protection layers on the metal surface and method for preparing the same and 0.05-6 parts carbonization-graphitization catalyst, calculated by weight. Also provided is method for preparing the same. The formulation provided here could create a friction-reducing and wear-resistant nanocrystal protection layer in situ on the metal friction and wear surface, at the same time, it has high hardness of cermet and elastic modulus of formulation which creates protection layers on the metal surface and method for preparing the same high grade alloy steel.
