Comparative analysis of peak-to-average power ratio (PAPR) reduction techniques for OFDM system
2013 4th International Conference on Computer and Communication Technology (ICCCT), 2013Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high-speed data transmission over multipath fading channels. 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.

Peak-to-Average-Power-Ratio (PAPR) Reduction Methods with Wavelet Transform in MIMO-OFDM
IETE Journal of Research, 2017ABSTRACTThis study is based on the comparison of the results with an analysis method recommended for the Peak-to-Average-Power-Ratio (PAPR) reduction methods. This is one of the most significant problems in the Multiple Input–Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems.

Peak-to-average power ratio (PAPR), fractional bandwidth and processing gain of UWB schemes
Eighth IEEE International Symposium on Spread Spectrum Techniques and Applications - Programme and Book of Abstracts (IEEE Cat. No.04TH8738), 2005This paper addresses the peak-to-average power ratio (PAPR), fractional bandwidth and processing gain of ultra-wideband (UWB) signals. First, the PAPR of UWB signals are derived and the numerical examples demonstrating PAPR values with Gaussian monocycle pulse shaping are presented.

Reducing peak-to-average power ratio (PAPR) using partial transmit sequence in OFDM systems
7th International Multi Topic Conference, 2003. INMIC 2003., 2005OFDM is a multicarrier system supporting high data rate transmission and generally requires no equalization at the receiver, making it simple and efficient. However, a drawback of this system is the large peak-to-average-power ratio (PAPR) of the transmit signal, which makes its straightforward implementation quite costly.

Peak to average power ratio (PAPR) reduction in OFDM systems
International Multi Topic Conference, 2002. Abstracts. INMIC 2002., 2002Summary form only given, as follows. One of the main limitations of OFDM systems is that it exhibits high Peak to Average Power Ratio (PAPR). It is desirable to reduce it as high PAPR causes saturation in power amplifiers thus leading to inter-modulation products among the sub carriers.

C2. Progressive Image Transmission over OFDM System with Minimum Peak-to-Average Power Ratio (PAPR)
2013 30th National Radio Science Conference (NRSC), 2013A modified Orthogonal Frequency Division MuItiplexing (OFDM) system for robust progressive image transmission is proposed in this paper. A joint sOUfce-channel coder (JSC C ) is employed in the modified OFDM system. The set partitioning hierarchical trees (SPTHT) used as SOUfce code, and The Low-Density Parity-C heck (LDPC ) used as a channel coder ...

Abstract Due to the evolution of mobile phone technology which enables the use of Internet, the demand for data rates has increased tremendously. Therefore, current 4G-LTE (long-term evolution) technology needs to be replaced in near future. Hence, currently possible solutions for 5G technology are heavily investigated.

Highly Efficient Transmitter for High Peak to Average Power Ratio (PAPR) Waveforms
2011Abstract : Aethercomm has shown that a high efficiency power amplifier can be developed to enhance efficiency over specific bands over frequencies ranging between 400MHz through 4000MHz with up to 67% efficiencies. These frequencies can be extended down to 30MHz and offer consistent performances by adding additional band functionality allowing support ...

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 ...
