Linear Precoding for PAPR Reduction of GFDMA

IEEE Wireless Communications Letters, 2016
Similar to the widely used orthogonal frequency division multiplexing systems, generalized frequency division multiplexing suffers from a high peak-to-average power ratio (PAPR). In this letter, we propose a data-independent precoder to minimize the variance of the instantaneous power (IP), subject to the constraint of unchanged average IP as a means ...

Receiver based PAPR reduction in OFDMA

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
High peak-to-average power ratio is one of the major drawbacks of orthogonal frequency division multiplexing (OFDM). Clipping is the simplest peak reduction scheme, however, it requires clipping mitigation at the receiver. Recently compressed sensing has been used for clipping mitigation (by exploiting the sparse nature of clipping signal).

PAPR Reduction in OFDM

International Journal of Emerging Research in Management and Technology, 2018
The term OFDM is a special type of FDM which has very vast application in the field of wired and wireless communication systems. In this paper we are discussing about the main problem of OFDM i.e. Peak to Average Power Ratio (PAPR) which affects the performance and efficiency of Power Amplifier.

Effects of PAPR reduction on HPA predistortion

IEEE Transactions on Consumer Electronics, 2005
There have been many papers concerning about the peak to average power ratio (PAPR) reduction and high power amplifier (HPA) linearization techniques for wireless OFDM communication systems. Few papers, however, make deep analysis on the relation between these two techniques.

Low-PAPR Multiplexing of Data and Pilots

2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016
Single-carrier frequency-division multiplexing (SC-FDM) has been adopted as the uplink (UL) waveform in the 3GPP LTE standards due to its various desirable features. One key benefit of SC-FDM is its low peak-to-average-power ratio (PAPR), which is highly desirable in the UL to lower down the cost of the power amplifier (PA) in the user equipment (UE ...

Enjoying the advantages of PAPRs.

Occupational health & safety (Waco, Tex.), 2009
For those who are hard to fit with a respirator, for those with facial hair, and to improve your employees' comfort and increase productivity, a PAPR may be just the respirator for your program. Do your homework, start with a small test group, and you may find that PAPRs deliver.
