چکیده
In this paper, a new non-redundant three-layer peak-to-average power ratio (PAPR) reduction technique is proposed for filter bank multicarrier communication based visible light (FBMC VLC) systems. the technique, FBMC VLC data signal overlapped with two signals. The initial-layer signals are modulated For PAPR reduction, second-layer constructed to decrease large-amplitude signals, while last-layer used improve small-amplitude do not overlap in frequency domain, because distributed on odd subcarriers, even subcarriers occupied by To mitigate effect of negative converted into positive, rather than being clipped off as conventional order realize trade-off between and bit error rate (BER), we introduce scaling factor performance calculated terms complementary cumulative distribution function (CCDF) BER. obtained results indicate that systems can achieve good BER outperforms corresponding orthogonal division multiplexing (OFDM)

Evaluation of Clipping Based Iterative PAPR Reduction Techniques for FBMC Systems
This paper investigates filter bankmulticarrier (FBMC), a multicarrier modulation technique exhibiting an extremely low adjacent channel leakage ratio (ACLR) compared to conventional orthogonal frequency division multiplexing (OFDM) technique. The low ACLR of the transmitted FBMC signal makes it especially favorable in cognitive radio applications, where strict requirements are posed on out-of-...
متن کاملReducing the PAPR in FBMC-OQAM systems with low-latency trellis-based SLM technique
Filter-bank multi-carrier (FBMC) modulations, and more specifically FBMC-offset quadrature amplitude modulation (OQAM), are seen as an interesting alternative to orthogonal frequency division multiplexing (OFDM) for the 5th generation radio access technology. In this paper, we investigate the problem of peak-to-average power ratio (PAPR) reduction for FBMC-OQAM signals. Recently, it has been sh...
متن کاملPAPR Reduction of FBMC by Clipping and Its Iterative Compensation
Physical layers of communication systems using Filter Bank Multicarrier (FBMC) as a modulation scheme provide low out-ofband leakage but suffer from the large Peak-to-Average Power Ratio (PAPR) of the transmitted signal. Two special FBMC schemes are investigated in this paper: the Orthogonal Frequency Division Multiplexing (OFDM) and the Staggered Multitone (SMT). To reduce the PAPR of the sign...
متن کاملPerformances Comparisons of Papr Reduction Scheme for Fbmc/oqam and Ofdm Systems
Multi-carrier transmission scheme such as OFDM (Orthogonal Frequency Division Multiplexing) has some disadvantages of large PAPR (Peak-to-Average Power Ratio) compared to a single carrier transmission scheme. Similar to other multicarrier systems like OFDM, a fundamental drawback of FBMC/OQAM(Filter Bank Multicarrier with Offset QAM) systems is the large PAPR of the signal. In this paper, we co...
