Peak to Average Power Ratio (PAPR) Reduction in OFDM System [PDF]
2006 International RF and Microwave Conference, 2006 Orthogonal Frequency Division Multiplexing (OFDM) is a special form of multi-carrier modulation which is robust against the multipath effect, Intersymbol Interference (ISI) and high spectral efficiency. However, Peak to Average Power Ratio (PAPR) is a major drawback in the system since this leads to the distortion problem in the linear devices such as ...

Optimized Peak to Average Power Ratio (PAPR) Reduction Technique for OFDM
2017 International Conference on Computing, Communication, Control and Automation (ICCUBEA), 2017Orthogonal Frequency Division Multiplexing (OFDM) is one of the widely used multicarrier technique for high speed data transmission. One of the main drawbacks of OFDM is the high Peak to Average Power Ratio (PAPR). It is the ratio of maximum power of the signal to its average power. Many techniques have been developed to lower the values of PAPR. Among

Performance Analysis of Peak-to-Average Power Ratio (PAPR) Reduction Techniques in an OFDM System
2012 Third International Conference on Computer and Communication Technology, 2012Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for wireless transmission due to its robustness against multipath fading. However, it has some limitations such as the Peak-to-average power ratio (PAPR), which restricts its use. It reduces the efficiency of the system.

Precoding technique for peak-to-average-power-ratio (PAPR) reduction in MIMO OFDM/A systems
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012The paper develops a new technique to reduce the peak to average power ratio (PAPR) in OFDM modulation for a MIMO system. The proposed method exploits the eigen-beamforming mode (EM) in MIMO systems which is a common feature in 4th generation standards: WiMAX and LTE.

Constant Modulus Algorithm for Peak-to-Average Power Ratio (PAPR) Reduction in MIMO OFDM/A
IEEE Signal Processing Letters, 2013A new peak-to-average power ratio (PAPR) reduction approach for MIMO-OFDM/A is developed based on the well-known constant modulus algorithm (CMA). This combines two ideas: 1) time domain signals from “resource blocks” (consisting of several subcarriers) may be linearly combined using precoding weights, transparent to the receiver; 2) the precoding ...

Partially clipping (PC) method for the peak-to-average power ratio (PAPR) reduction in OFDM
2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat. No.04TH8754), 2005OFDM (orthogonal frequency division multiplexing) has emerged as one of the best modulations for broadband mobile communications. Despite its robustness against multipath interference, the drawback of peak-to-average power ratio (PAPR) has to be overcome.
