Reduction of the peak to average power ratio (PAPR) for DVB systems using Gaussian based tone reservation and unused tones

China-Ireland International Conference on Information and Communications Technologies (CIICT 2007), 2007
One of the major drawbacks of OFDM is its high peak-to-average power ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplifier. Tone reservation (TR) is a technique designed to combat this problem by reserving a number of sub-carriers (tones) in the frequency domain to generate a cancellation signal in ...

Peak to Average Power Ratio (PAPR) Minimizing Techniques for Helical Interleaved OFDM System

2017
Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier, multi rate, multi symbol, frequency division multiplexing transmission system. In which a single high data rate stream is divided in to a number of low data rate streams. High spectral efficiency due to orthogonal subcarriers is the major advantage of this system.

Comparative Study of the Performances of Peak-to-Average Power Ratio (PAPR) Reduction Techniques for Orthogonal Frequency Division Multiplexing (OFDM) Signals

2018
In this paper, two distortionless PAPR reduction techniques, Selected Mapping (SLM) and Partial Transmit Sequences (PTS), are compared in terms of PAPR reduction capability and computational complexity for equal number of candidate OFDM symbols. Using MATLAB simulation, it is shown that SLM outperforms PTS in PAPR reduction capability. For small values
