Abstract: Embodiments of a radio-circuit apparatus are generally described herein. The radio-circuit apparatus may comprise circuitry to generate an output baseband signal to reduce one or more localized peak power levels of an input baseband signal. The output signal may be based on a difference between an input baseband signal and an excess signal. The radio-circuit apparatus may further comprise a hard clipper circuit to restrict power levels of the input baseband signal to a clip range to generate a clipped signal. The radio-circuit apparatus may further comprise one or more filters to filter a predicted OOB emission signal in accordance with a target OOB emission spectrum. The predicted OOB emission signal may be based on a difference between the input baseband signal and the clipped signal.
