Whale optimization‐based PTS scheme for PAPR reduction in UFMC systems

IET Communications
This paper proposes a whale optimization algorithm (WOA)‐based partial transmit sequence (PTS) scheme called WOA‐PTS to reduce the high peak‐to‐average power ratio (PAPR) for universal filtered multi‐carrier (UFMC) systems.

UFMC Transceiver Complexity Reduction [PDF]

2018 25th International Conference on Telecommunications (ICT), 2018
UFMC is a candidate waveform technology for 5G wireless systems and beyond. It combines the simplicity of OFDM with the advantages of FBMC. However, these advantages come together with an increase in the complexity at the transmitter caused by the implementation of a filter and applying an FFT for each sub-band, whereas at the receiver it is due ...

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

IET Radar, Sonar &Navigation, Volume 17, Issue 1, Page 47-62, January 2023., 2023
Abstract 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, which eventually lead to the degradation of the performance of the joint radar ...
