Abstract: In this paper, we investigate the peak-to-average power ratio (PAPR) issue in orthogonal frequency division multiplexing (OFDM) and beyond fifth-generation (B5G ... In the UFMC example, when ...

Abstract: In this letter, we conduct an experiment of quantum noise stream cipher scheme based on 3-channel-QAM mapping and DFTs-OFDM in optical back-to-back and 160km standard single mode fiber. The ...

MATLAB Imitation Modeling for the BER of the Satellite Communication System using QPSK and OFDM Modulation with LS Channel Estimation based on Pilot Signals in the Transionospheric Communication ...

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers ... Since most of these algorithms are coded in “C” or tools like Matlab, it is important to have a verification ...

Figure 5. Simulated CCDF curves as a function of PAPR. The 3GPP standards ratified in December 2017 converged towards using cyclic prefix OFDM (CP-OFDM) as the waveform of choice for 5G non-standalone ...
