An Adaptive Coding Technique For PAPR Reduction
IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007In this work, we present an adaptive technique to reduce high peak-to-average power ratio in coded orthogonal frequency division multiplexing. High peak-to-average power ratio has been a primary hurdle for the use of orthogonal frequency division multiplexing in low cost applications.

Papr Reduction for Beamforming Ofdm Transmitters
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006A high peak-to-average-power ratio (PAPR) is a primary drawback of orthogonal frequency-division multiplexing (OFDM). Many methods have been proposed to reduce the OFDM PAPR for single-antenna and for MIMO systems. Some systems, however, use multiple antennas for frequency-selective transmit beamforming either to a single or multiple simultaneous ...

Intelligent interleaver for PAPR reduction
2008 Second International Conference on Electrical Engineering, 2008In orthogonal frequency division multiplexing (OFDM) systems, one of the major problems to be tackled is high peak to average power ratio (PAPR). In this paper a PAPR reduction scheme for OFDM system is proposed that takes the advantage of the classification capability of learning vector quantization (LVQ) networks.

PAPR reduction in OFDM systems
2014 Annual IEEE India Conference (INDICON), 2014In a communication system, operation of the transmitter power amplifier is limited to linear range. Input signal with an amplitude more than the transmitter power amplifier linear range results in signal distortion. Hence, the input signal to the transmitter should be with low peak to average power ratio.

PAPR reduction of OFDM by random phase updating
The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003A novel random phase updating algorithm for peak-to-average power ratio (PAPR) reduction of the OFDM signal is addressed. The phase of each subcarrier is updated by a random increment until the PAPR goes below a certain threshold level. The influence of different distributions for the phase increments and the variance of distributions on the mean and ...

Improved SLM for PAPR Reduction in OFDM System
2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007Selected mapping (SLM) is a promising peak-to-average power ratio (PAPR) reduction technique for orthogonal frequency division multiplexing (OFDM) system. In SLM, phase sequences are combined with the data for generating alternative signals, so as to reduce the PAPR.

PAPR Reduction Technique In OFDM
2016Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier transmission scheme it transmits large data over radio wave. PAPR is one of the disadvantage of OFDM system. (Peak to average power ratio) PAPR is nothing but several sinusoidal leads.

A method for PAPR reduction in MSE-OFDM systems
20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06), 2006High peak to average power ratio (PAPR) of the transmitted signal is a major drawback of multicarrier transmission such as orthogonal frequency division multiplexing (OFDM). This work considers the problem of PAPR reduction in a multi-symbol encapsulated OFDM (MSE-OFDM) system. This paper employs the discrete cosine transform (DCT) to the data sequence.
