Low-Complexity Selective Mapping Methods for Multicarrier Faster-Than-Nyquist Signaling

open access: yesIEEE Access, 2020
Multicarrier faster-than-Nyquist (MFTN) signaling is a high spectral efficiency transmission scheme, which is promising in the future communication. One of the major problems of MFTN signaling is high peak-to-average power ratio (PAPR).

Numerology Scheduling for PAPR Reduction in Mixed Numerologies

open access: yesIEEE Wireless Communications Letters, 2021
The flexible mixed-numerology structure with orthogonal frequency division multiplexing (OFDM) waveform is a key enabler to meet the requirements of various applications in fifth-generation (5G) and beyond wireless networks. However, the high peak-to-average power ratio (PAPR) is still one of the main drawbacks and conventional numerology selection can

PAPR Reduction Scheme for OFDM

open access: yesProcedia Technology, 2012
AbstractThis paper focused on peak to average power ratio (PAPR) reduction scheme for OFDM system. OFDM has several properties which make it an attractive modulation scheme for high speed transmission. the main draw back of OFDM is high PAPR. The high PAPR causes the interference and degraded the performance of the system while OFDM signal pass through
