A New Peak Clipping Algorithm for PAPR Reduction in OFDM
The peak-to-average-power ratio (PAPR) is one of the major problems of Orthogonal Frequency Division Multiplexing (OFDM) systems. Various PAPR reduction techniques have been given in the past. Among these techniques, the clipping technique has been widely adopted as a practical scheme because of its low computational complexity and simplicity in implementation, while the pre-coding technique is...
متن کاملReduction of Papr in Ofdm by Clipping
One of the main disadvantages of Orthogonal frequency division multiplex (OFDM) is high peak-to-average power ratio (PAPR). The clipping method of PAPR reduction is analyzed in this article.
متن کاملClipping Technique for BER and PAPR Reduction in OFDM System
Peak to Average Power Ratio (PAPR) is one of most detrimental aspects in any wireless communication system using multicarrier modulation technique like OFDM, which cause power degradation and spectral spreading. Due to the simplest way for PAPR reduction, clipping technique has been proposed and seems to be promising for use in commercial system. In this paper, we mainly focus on Amplitude clip...
متن کاملClipping Versus Symbol Switching for PAPR Reduction in Coded OFDM
In multicarrier systems, the transmitted timedomain signal exhibits large amplitude peaks. This peak-toaverage power ratio (PAPR) problem complicates the practical use of multicarrier systems: the amplifier used to transmit the signal saturates because of the large peaks and causes non-linear distortion. As this non-linear distortion frustrates severely the detection of the multicarrier signal,...
متن کاملPAPR Reduction in OFDM using Clipping and Filtering
Abstract: Orthogonal Frequency Division Multiplexing (OFDM) is an emerging field of research in the field of wireless communication and finds its application where high data rate is required at low latency and better spectral efficiency. Peak to Average Power Ratio (PAPR) is the limiting factor for an OFDM system as it degrades the system performance by reducing SQNR of ADC/DAC as well as affec...
