Efficient Application of Selected Mapping with Clipping for PAPR Reduction in OFDM Systems
ISSN 2277 5080 | © 2014 Bonfring Abstract--Orthogonal Frequency Division Multiplexing (OFDM) is an inimitable technology in wireless communication. High peak-to-average power ratio (PAPR) is a challenging issue in OFDM system. Large PAPR results in significant distortion in OFDM signal when passed through nonlinear high power amplifier. Selected mapping (SLM) is an efficient technique to reduce...
متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

متن کاملPAPR Reduction of OFDM Signal with Improved Selected Mapping and Clipping Techniques
OFDM is one of the proven multicarrier modulation techniques, which provides high spectral efficiency, low implementation complexity, less vulnerability to echoes and non-linear distortion. This technique is used by almost all 3G wireless standard and above. The every technique has some pit fall. The one major shortcoming in the implementation of this system is the high peak-to-average power ra...
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.
