PAPR Distribution Analysis at the Output of Nonlinear PAPR Reducers
Nonlinear PAPR reducers, such as clipping and companding techniques, are some simple methods used to reduce the Peak-to-Average Power Ratio (PAPR). In this paper, assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we investigate the PAPR distribution of an OFDM signal when it is passed through a nonlinear PAPR reducer. The obtained PAPR distribut...
متن کاملTo PAPR or not to PAPR?
The present outbreak of Ebola has health care professionals seeking guidance on isolation precautions for routine care and aerosol-generating procedures (AGPs). The most recent guidelines state that during AGPs, health care professionals should wear respiratory protection at least as protective as a National Institute for Occupational Safety and Health-certified fit tested N95 filtering face pi...
متن کاملAnalysis and Comparison of PAPR Reduction Techniques in OFDM Systems
The destructive impact of fading environments and also bandwidth limitations are two main challenges which communication is dealing with them. These challenges can affect on the growth of wireless communication and even cause reliable communications and high data rate to be prevented. Thus, OFDM (Orthogonal Frequency Division Multiplexing) modulation by using of fast calculation hardwares such ...
متن کاملDistribution of the PAPR for Real-Valued OFDM Signals
In the literature, the bounds of the peak to average power ratio (PAPR) are generalized to both complex-valued and real-valued orthogonal frequency division multiplexing (OFDM) signals. In fact, these bounds are accurately bounding the PAPR distribution of complex-valued OFDM signals only. In this paper, we derive accurate PAPR bounds of real-valued OFDM signals and show that bounds of complex-...
متن کاملAnalysis of PAPR reduction Techniques for OFDM
In this paper, a joint solution is proposed with RS coding, OFDM, and PAPR clipping. We implemented the hybrid method which consists of RS coding and adaptive clipping technique over an additive white Gaussian noise (AWGN) channel. Reed Solomon RS (255, 239) coding can correct 8 symbol errors from 239 symbols data. This capability can effectively compensate for the performance degradation resul...
