IET Communications, Volume 19, Issue 1, January/December 2025.This article proposes a hybrid SLM+PTS+RNN algorithm to mitigate the high PAPR challenge in UFMC systems for B5G networks. The method significantly improves power efficiency (by 30%–40%) while maintaining BER and PSD performance, outperforming traditional PAPR reduction techniques.

Receiver design for CDMA‐FBMC/ OQAM systems [PDF]
Electronics Letters, 2020 This Letter documents BER performance analysis of orthogonal affine precoder (OAP)‐based CDMA filter bank multi‐carrier offset QAM (CDMA‐FBMC/OQAM) systems. The use of OAP cancels the interference introduced by simultaneous transmission of data and training sequence during channel estimation and data detection.

Joint Symbol Timing and Channel Estimation for FBMC-OQAM Systems [PDF]
IEEE Access, 2019 Filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) can achieve very low out-of-band radiation and is considered to be an important candidate waveform for future communication networks. However, the synchronization sequence design and channel estimation issues are complicated in FBMC-OQAM systems owing to the pulses overlap
