Hybrid Peak-to-Average Power Ratio Reduction Techniques: Review and Performance Comparison

Peak-to-Average Power Ratio Reduction Techniques for OFDM Signals

Orthogonal frequency division multiplexing (OFDM) has been adopted as a standard for many modern wireless applications requiring high data rate due to bandwidth efficiency, resistance to frequency selective fading and simple digital realization using IFFT/FFT operations. However, physical implementation of the OFDM system suffers from several difficulties. One of the major limitations of OFDM i...

Peak to Average Ratio Reduction for Multicarrier Transmission: a Review

Peak 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.

Comparative Study of Peak-to-Average Power Ratio Reduction Techniques for OFDM System

Orthogonal Frequency Division Multiplexing (OFDM) is one well-known scheme, which has recently become a preferred choice for parallel-data-transmission which reduces the influence of multipath fading and avoids the use of complex equalizers. However, an OFDM signal has a large peak-to-average power ratio (PAPR), which can result in significant distortion when transmitted through a nonlinear dev...
