Diversity DNA Encryption in Layered PTS with FBMC OQAM Systems

In Multi-carrier modulations, the Partial Transmit Sequence (PTS) is a useful way for achieving a low Peak to Average Power Ratio (PAPR). The Filter Bank Multi-carrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) approach has been shown to be a promising technology in advanced wireless communication. The DFT spread Layered PTS (LPTS) method effectively condenses the PAPR of the FBMC/OQAM signal. In addition, a diversity deoxyribonucleic acid (DNA) chaotic encryption approach is presented in conjunction with the layered PTS scheme to improve the physical layer security of the FBMC/OQAM system. Following encryption of the input original binary bit stream, it is modulated with FBMC/OQAM. The bit data encryption process is dynamically regulated by chaotic sequences which are created by a hybrid chaotic system. It is built with improved-Logistic systems which increase the resilience against harmful attacks by unlawful attackers. The results demonstrate that the Layered PTS approach based on diversity DNA encryption may successfully assure the security of transmitted data.
