Pre-cursor extended RAM-DFE canceler (PERC) nonlinear equalizer for nonlinear ISI channels
1998 (English)In: Proceedings 1998 DSP Workshop, IEEE Signal Processing Society, 1998Conference paper, Published paper (Refereed)
Abstract [en]

We consider a nonlinear equalizer structure that provides effective and computationally efficient intersymbol interference (ISI) reduction for channels with nonlinearities. The technique makes use of a RAM-DFE structure enhanced with the ability to cancel pre-cursor nonlinear ISI. In many nonlinear channels, the distortion caused by the nonlinear element (such as a nonlinear power amplifier) and bandlimiting filters creates nonlinear ISI. Such distortion typically limits the system to loworder constellations (such as QPSK). Higher order constellation are possible only if effective reduction of the nonlinear ISI is achieved. The applicability of our nonlinear equalizer and its performance for a nonlinear satellite channel is included.
