A novel PTS-based PAPR reduction scheme for FBMC-OQAM system without extra bit transmission of SI

In this paper, a Novel Partial Transmit Sequence-based scheme is proposed, namely (N-PTS). The aim is to solve the major hindrance of high Peak to Average Power Ratio (PAPR); as well as to combat the overlapping structure issue affecting Filter Bank Multicarrier system based on the Offset Quadrature Amplitude Modulation (FBMC-OQAM). On that note, computational complexity is also reduced. The proposed scheme uses FBMC-OQAM signal in the frequency domain. To this end, the lowest PAPR value is calculated from data located in a Storage Device (SD). Accordingly, it is properly identified through its location referred to as 'Row' which consists of the Side Information (SI) to recover the original signal at the receiver. As a result, a substantial reduction in PAPR and computational complexity are achieved. Finally, it is found necessary to mention that SI is claimed not to require extra bits to be transmitted, using phase offset with Minimum Euclidian Distance (MED) criterion, while the Bit Error Rate (BER) performance remains very satisfactory.

Automated summary

This paper proposes a novel N-PTS scheme to address the issues of high PAPR and overlapping structure in the Filter Bank Multicarrier system, while reducing computational complexity. The scheme utilizes FBMC-OQAM signals and calculates the lowest PAPR value from data in a Storage Device, using side information to recover the signal at the receiver end effectively. There is no need for extra bits to be transmitted, and the performance in terms of BER remains satisfactory.
