Electronics Letters, Volume 60, Issue 18, September 2024.In the current most powerful filter‐bank multi‐carrier comb spectrum framework, a parameter‐agile time–frequency structure between symbols is elaborated to improve the uncertainty of waveform generation architecture. Furthermore, a novel composite modulation strategy that combines intra‐symbol chaos‐based radar frequency modulation and inter‐symbol ...

Whale optimization‐based PTS scheme for PAPR reduction in UFMC systems
IET Communications, Volume 18, Issue 2, Page 187-195, January 2024.This paper combines the whale optimization algorithm with partial transmit sequence, a probabilistic method of peak‐to‐average power ratio reduction, to solve the peak‐to‐average power ratio problem partial transmit sequence. Abstract This paper proposes a whale optimization algorithm (WOA)‐based partial transmit sequence (PTS) scheme called WOA‐PTS to

Joint Sparse Graph for FBMC/OQAM Systems [PDF]
IEEE Transactions on Vehicular Technology, 2018 As an advanced non-orthogonal multiple access (NOMA) technique, the low density signature (LDS) has never been used in filter bank multicarrier (FBMC) systems. In this paper, we model a low density weight matrix (LDWM) to utilize the intrinsic interference in FBMC systems when single-tap equalization is employed, and propose a LDS-FBMC scheme which ...
