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 ...

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.

Coding Schemes Applied to Peak-to-Average Power Ratio (PAPR) Reduction in OFDM Systems
2008 International Wireless Communications and Mobile Computing Conference, 2008High PAPR of the transmitted signal is a major drawback in the OFDM systems. In this paper, coding schemes are proposed to reduce high PAPR One is using parity check coding scheme, and the other is using selected mapping (SLM) applied scheme. With parity check coding scheme, the parity information is used to expand the signal space.

Peak-to-Average Power Ratio (PAPR) Reduction by Pulse Shaping Using the K-Exponential Filter
IEICE Transactions on Communications, 2010A K-exponential filter is derived and utilized for pulse shaping to reduce peak to average power ratio (PAPR) without intersymbol interference (ISI). While keeping the same bandwidth, the frequency responses of the filters vary with different values of the parameter k.

Peak to Average Power Ratio (PAPR) reduction in OFDM for a WLAN network using SLM technique
2011 3rd International Conference on Electronics Computer Technology, 2011Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. OFDM modulation schemes offer many advantages for multicarrier transmission at high data rates over time dispersive channels, particularly in mobile applications.

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), 2004OFDM (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.

Peak-To-Average Power Ratio Analysis For Embedded Pilot And Superimposed Pilot Aided OTFS Waveform
2023 IEEE Guwahati Subsection Conference (GCON), 2023Peak-to-average-power-ratio (PAPR) is one of the key performance metrics for Orthogonal time-frequency space (OTFS) waveform which critically depends on its transmit frame structure. On the other hand, estimation of the wireless channel in delay-Doppler (
