Abstract:
An adaptive filtering system for processing a received signal, comprising:a signal processor having plural states, said received signal being applied to an input of said signal processor, said signal processor generating a processed signal in accordance with a selected one of said states; a slicer connected to receive said processed signal for producing a pulse signal from said processed signal as an output signal of said adaptive filtering system; a eye-diagram calculator connected to receive said pulse signal for producing a metric signal which is a function of a minimal separation between leading and trailing edges of a succession of n pulses in said pulse signal superimposed upon one another within a repetitive sampling window; an adaptive controller responsive to said metric signal for determining one of said plural states of said signal processor that optimizes said metric signal, and for causing said signal processor to be in said one state.
