RECORDING DEVICE SINGLE elements using fuzzy logic methods

摘要

The invention relates to communication technique, particularly to devices designed for value decision obtained binary digital signal. The apparatus by use of the block defining the scale fuzzy density distribution time points samples blocks forming membership functions of the reception of "logic 0" and "logic 1", two maxi mine compositions and correction apparatus devices allows to increase the reliability of the devices receiving a decision to register unit cell (Ee) - "logic 0" and "logic 1" - in the absence of a priori probability and statistical information about the state of Ee in the presence boundary distortion and fragmentation Ee. For this purpose the device obtained after sampling the signal samples correspond to the membership functions which characterize the "good" reception "logic 1" or "logic 0"; carried out the procedure for solving the fuzzy integral, then a decision is made for admission to a binary one or zero. To increase the reliability of the reception Ee at the interface between the decision takes into account the presence of uncertain reception area, in contact with which a decision is made about the reception of a signal "erase".
