Prototype of a Peak to Average Power Ratio Reduction Scheme in Orthogonal Frequency Division Multiplexing Systems
Peak to average power ratio (PAPR) is one of the main imperfections in the broadband communication systems with multiple carriers. In this paper, a new crest factor reduction (CFR) scheme based on interleaved phase sequence called Dummy Sequence Insertion Enhanced Partial Transmit Sequence (DSI-EPTS) is proposed which effectively reduces the PAPR while at the same time keeps the total complexit...
متن کاملPeak to Average Power Ratio reduction method for Orthogonal Frequency Division Multiplexing in 4G Communication
Recent development in data communication applications, the role of Orthogonal Frequency Division Multiplexing (FDM) technology is unavoidable. The OFDM system improves the multipath fading channel and bandwidth in effective manner. But the main problem in OFDM is large fluctuations. This often affected the design performance and produces the poor results when compared to the existing methodolog...
متن کاملLow-complexity peak-to-average power ratio reduction method for orthogonal frequency-division multiplexing communications
The high peak-to-average power ratio (PAPR) of the transmitted signal is a major drawback of multicarrier transmission such as orthogonal frequency-division multiplexing OFDM. A plethora of PAPR reduction techniques has been reported in the literature. Some of the techniques modify the phase and/or amplitude of symbols in the original symbol alphabet (SA) such as selected mapping and partial tr...

Orthogonal Frequency Division Multiplexing (OFDM) has been used in many advanced wireless communication systems due to its high spectral efficiency and robustness to frequency selective fading channels. However, the major concern with OFDM system is the high peak-to-average power ratio (PAPR) of the transmitted signal. Some of the popular techniques used for PAPR reduction in OFDM system are co...
متن کاملEffective Performance Analysis of Peak Power Reduction in Orthogonal Frequency Division Multiplexing System
Orthogonal Frequency Division Multiplexing (OFDM) is a digital transmission method developed to meet the increasing demand for higher data rates in communications which can be used in both wired and wireless environments. Coding, Phase rotation and Clipping are among many PAPR reduction schemes that have been proposed to overcome this problem. In this paper, we are analysed on three different P...
