Abstract
Signal-to-noise ratios (SNRs) and/or amplifier performance can be improved in crest factor reduction (CFR) applications by steering clipping noise in a different direction than the data signal achieving upon reception. Indeed, using clipping noise signals that have a different amplitude-phase relationship than the input/baseline signal causes the clipping noise signal and data signal to exhibit different antenna patterns, effectively steering the clipping noise in a different direction than the data signal. For instance, clipping noise can be steered away from potential receivers to improve received signal quality. In addition, higher magnitude clipping noise can be used to achieve improved power amplifier performance without increasing received SNR.
