A New Clipping Function for PAPR Mitigation: The Gaussian Clipping Function

Authors:

Keywords: PAPR; Clipping; Gaussian Clipping

Abstract:
A Gaussian function to clip multicarrier modulation is presented in this paper in order to decrease their Peak to Average Power Ratio (PAPR). The Gaussian clipping (GC) function is a soft non-linear function which keeps constant the average power of the signal, what is a characteristic of great importance in real transmission. The characteristics and performance of this GC is analysed both theoretically and by simulation. Furthermore, in the application context of Wifi IEEE802.11, this GC is compared to several other clipping functions well known in the literature such as hard clipping, smooth clipping, and deep clipping. The results prove that the average power is kept constant which was our objective
