Optimization of PAPR for OFDM Systems Using Clipping and Tone Reservation
OFDM System has a significant disadvantage that is large PAPR leading to lower power proficiency and non-linear distortion at the transmit power amplifier. There are various techniques to reduce PAPR. Clipping using Tone Reservation (TR) with SDR is incorporated in this paper. Tone reservation (TR) is one of the alluring techniques to reduce peak-to-average power ratio (PAPR) in OFDM. It brings about computational complexity that increments exponentially with the number of subcarriers. Also, clipping fundamentally cuts off the random peaks that show up in an OFDM System and reduces the PAPR. The simulation results show that clipping and tone reservation is a proficient method to reduce PAPR with SDR implementation.
