Abstract
NB-IoT, short for NarrowBand IoT, is a communication standard for long-range connectivity of numerous devices. A key research area in NB-IoT is reducing Peak-to-Average Power Ratio (PAPR).
NB-IoT builds on 4G LTE (Long Term Evolution) and employs Single Carrier Frequency Division Multiple Access (SC-FDMA) in UpLink (UL) to minimize PAPR. To address power amplifier non-linearities, we propose applying the “clipping” technique, borrowing from OFDM.
In this paper, we examine the impact of Clipping Factor (CF) on PAPR reduction and the attenuation factors of Raised-Cosine (RC) filter and the Root Raised-Cosine (RRC) filter on PAPR probability distribution. Our analysis demonstrates a 2.5 dB (33.33%) reduction at a cumulative distribution function of(10^{-3}), with better results when using the Raised-Cosine (RC) filter.
