However, OFDM suffer from some obstacles during data transmission, the main one is the high peak-to-average power ratio (PAPR), which leads to saturate the power amplifier, generate more interference and reduced resolution of nonlinear components like digital/analog converters. The partial transmit ...
Peak-to-Average Power Ratio In subject area: Engineering The PAPR is defined as the peak power within one DFT block (one OFDM symbol) normalized by the average signal power. From: 4G: LTE/LTE-Advanced for Mobile Broadband (Second Edition), 2014 About this pageSet alert Discover other ...
Peak-to-Average Power Ratio in OFDM Systems A major problem in multicarrier modulation is the high peak-to-average power ratio (PAR) that occurs in the modulated signal. Generally, large signal peaks in the transmitted signal occur when the signals in the K subchannels add constructively in p...

Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier system supporting high data rate transmission and generally requires no equalization at the receiver, making it simple and efficient. One of the challenging issues for OFDM system is its high Peak-to-Average Power Ratio (PAPR). The...

Given so, the peak to average power ratio for an OFDM system with subcarriers and all subcarriers are given the same modulation is, . It is reasonably intuitive that the above value corresponds to the maximum value of PAPR (when all the subcarriers are equally modulated, all the subcarriers...
Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high data rate transmission in wireless and wired applications. However, implementation of theOFDM system entails several difficulties. One of the major drawbacks of OFDM is the high peak to average power ratio (PAPR...
