A Low Complexity Partial Transmit Sequence for Peak to Average Power Ratio Reduction in OFDM Systems [PDF]
Radioengineering, 2011 Partial transmit sequence (PTS) is one of the most important techniques for reducing the peak to average power ratio (PAPR) in OFDM systems. This paper presents a low complexity PTS scheme by applying a new phase sequence.

PEAK TO AVERAGE POWER RATIO REDUCTION TECHNIQUES
International Journal of Computer Science and Mobile Computing, 2022 The most extensively used wireless communication system Multiple input multiple affair and orthogonal frequency division multiplexing because of their large benefits and advantages. MIMO OFDM has a major debit which makes the system noisy because of the harpoons in the transmitting signal. Harpoons produce noice and deformation. Different ways are used

Generalized Discrete Fourier Transform for FBMC Peak to Average Power Ratio Reduction
IEEE Access, 2019 Filter bank multicarrier (FBMC) is a strong candidate as a waveform based technique in advanced wireless communication systems (e.g. 5G), as an alternative to orthogonal frequency division multiplexing (OFDM). Like all multicarrier modulation techniques,

CLIPPING TECHNIQUES FOR PAPR REDUCTION IN FBMC/OQAM SYSTEM OVER DOUBLY-SELECTIVE CHANNELS
Journal of Engineering and Sustainable Development, 2021 One of the major disadvantages of Filter Bank Multicarrier (FBMC) is high Peak-to-Average Power Ratio (PAPR) of transmitted signal. As a result, nonlinear power amplifier (PA) properties, considerable out-of-band and the in-band distortion types take ...
