Abstract: The transversal equalizer with tap-spacing set for adaptive minimization of intersymbol interference in a synchronous digital data transmission system is modified to provide simultaneous shaping of the signal frequency spectrum. Adaptively variable tap gains for time domain equalization are augmented by fixed tap gains for frequency domain signal shaping. Signals from fixed and variable gain attenuators, relatively delayed by a fractional symbol interval with respect to each other, are combined to form optimized output signals. The respective fixed and variable gain contributions thus act substantially independently in accomplishing spectral shaping and intersymbol interference minimization due to their staggered relationships.
