Analysis 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 کاملIs PAPR reduction always justified for OFDM?
The justification of implementing PAPR reduction schemes in OFDM is discussed. Decreasing PAPR increases the efficiency of the linear power amplifier, yielding an increase in average power emitted and consequentially an increase in capacity. However, implementing a PAPR reduction scheme s such as Tone Reservation or Selective Mapping means a decrease in the payload bandwidth which causes a decr...
متن کاملPAPR Reduction in Wireless OFDM Systems
Non-linear programming has been extensively used in wireless telecommunication systems design. PAPR reduction is implemented in the handheld devices and low complexity is a major objective. High PAPR is one of the major disadvantages of OFDM system which is resulted from large envelope fluctuation of the signal. Our proposed technique to reduce the PAPR is based on constellation shaping that st...
متن کاملPerformance Evaluation for OFDM PAPR Reduction Methods
The ultimate goal of Peak to Average Power Ratio (PAPR) reduction for Orthogonal Frequency Division Multiplexing (OFDM) signals is to reduce the signal’s sensitivity to nonlinearity and to improve signal quality and transmitter power efficiency. Performance evaluation has traditionally been based mainly on the PAPR distribution curves. For clipping related methods, however, tradeoffs between PA...
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...
