JUDGING FEEDBACK EQUALIZER AND TWO INPUT JUDGEMENT SLICE SETTING METHOD

摘要

PURPOSE: To lower the required S/N ratio by optimizing a judgement slice being employed in two input judgement including the adjacent bit information. ;CONSTITUTION: A two input judgement unit 108 employs any one of Figures B-E at the judgement slice setting section thereof. In the case of Fig. B, the setting section sets a line 124 passing the origin and extending, respectively, in parallel with parallel lines 120, 122 connecting two coordinates A, B and C, D which are judged as -1 and +1 by an input coordinate (f, g) under a noiseless state, as a judgement slice.;COPYRIGHT: (C)1996,JPO
