Peak to Average Power Ratio Based Signal Detection for Frequency Shift Multitone SWIPT System
IEEE Access, 2021 In this paper, we investigate a multitone simultaneous wireless information and power transfer (SWIPT) based modulation scheme for battery-less Internet of Things (IoT) nodes that works in the ultra high frequency (UHF) region.

On the peak-to-average power ratio of M-sequences
Finite Fields and Their Applications, 2006 Let \(\mathbb F_q\), \(q=2^m\), be a finite field with a primitive element \(\alpha\). For \(\beta\in \mathbb F_q^*\), the \(M\)-sequence is: \[ a_k(\beta )=(-1)^{\text{tr}(\beta\alpha^k)},\qquad 0\leq k < q-1, \] where \(\text{tr}\) is the trace form \(\mathbb F_q\) to \(\mathbb F_2\).

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 ...
