Peak-to-average power ratio reduction of OFDM signals using pulse shaping
This paper proposes an efficient technique for reducing the PAPR of OFDM signals. The proposed technique is very effective and avoids the use of extra Inverse Fast Fourier Transformations (IFFTs) as was done in some previously published techniques but instead is based on a proper selection of the time-limited waveforms of the different subcarriers. Thus, its implementation complexity is also mu...
متن کاملPeak to Average Power Ratio Reduction in Mc Cdma System by Using Pulse Shaping Technique
One of the drawback of multicarrier code division multiple access (MC CDMA) is the high peak to average power ratio (PAPR). In this paper A novel scheme based on pulse shaping described for PAPR reduction. Here three different pulse shaping filters (Raised cosine, Sinc power pulse and Nyqist pulse) are described for PAPR reduction in MC CDMA system. The method is based on the proper selection o...

متن کاملPeak to Average Power Reduction Technique in OFDM System
In this paper, OFDM based on Software-Defined Radio (GNU Radio) to reducing the peak to average power ratio is developed and tested. Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, whether wireless or over copper wires, used in applications such as...
متن کاملPeak to average power ratio reduction of OFDM signals using peak reduction carriers
A technique is described for a better than 5 dB reduction in the Peak to Average Power Ratio (PAPR) of an OFDM signal. The optimal amplitude and phase of additional peak reduction carriers (PRC) is obtained using a codebook, which is obtained using a search of all possible signal combinations.
