Abstract:
According to various embodiments, methods, apparatuses and systems are provided to allow a transmitter to reduce the Peak to Average Power Ratio (PAPR) of a modulated signal by applying a pre-emphasis filter to the signal, clipping the pre-distorted signal to reduce the PAPR, and applying a de-emphasis filter to the clipped signal to reduce the spectral leakage caused by the clipping. Other embodiments may be disclosed or claimed.
