Joint Active User Detection, Timing Offset and Channel Estimation for FBMC‐Based Uplink Massive Access Systems

IET Communications, Volume 19, Issue 1, January/December 2025.
The robustness against timing offsets of filter bank multi‐carrier (FBMC) is appealing for grant‐free massive access scenarios that mainly adopt asynchronous transmissions. In this work, we propose a compressed sensing based algorithm for joint active user detection as well as timing offset and channel estimation in uplink communication under the ...

Reducing the Peak to Average Power Ratio of UFMC Waveform for Beyond 5G System Using Hybrid SLM+PTS+RNN Algorithms

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.

Distortion analysis in OQAM/FBMC-based OFDMA [PDF]

2015 IEEE 16th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2015
The paper considers an OFDMA scheme based on OQAM/FBMC and evaluates the interaction of the different users to one another under strong frequency selectivity or timing synchronization errors between users. More specifically, due to imperfect equalization, each user contributes to a distortion component in the received signal.

Joint radar communication system design based on filter bank multicarrier modulation scheme

IET Radar, Sonar & Navigation, 2023
Since orthogonal frequency division multiplexing (OFDM) signals are sensitive to Doppler shift, OFDM signals with cyclic prefix (CP) not only reduce the communication rate but also result in symmetric pseudo peaks in the ambiguity function of the radar ...
