Filter bank multicarrier (FBMC) based on offset quadrature amplitude modulation (OQAM) is regarded as the prospective system for mobile communication. To utilize the potential of the system, the issues like carrier frequency offset have to be investigated extensively. The modulations in the multicarrier system draw a great interest among researchers and engineers in the telecommunication field. Despite the OFDM advantages, significant disadvantages in the system enable researches to approach into efficiently evolved FBMC system. In this paper, the detrimental effects caused by carrier frequency offset on the received signal is considered. Carrier Frequency Offset (CFO) compensation has been effectively undertaken by modified Kalman filtering. The compensation technique not only depends on the specific FBMC modification but also influenced by the selected receiver. A comprehensive analysis of the frequency offset response under three conditions (without offset, with offset, and the compensated samples) has been performed in the proposed system with performance measures as bit error rate (BER) and signal-to-noise ratio. 9 CFO compensation is analyzed by varying the channel characteristics (additive white Gaussian noise [AWGN] and Rayleigh Fading) and subcarrier filtering (prototype filter, Gaussian filter, and root-raised coefficients). From the overall analysis, it is observed that the BER varies from 0.1 to 0.001.

“…The filter bank multicarrier/offset quadrature-amplitude (FBMC/OQAM) modulation technology is designed with a proper prototype filter, which eliminates the need to introduce CP and guard intervals in the system. In addition, FBMC has the advantages of robustness against narrowband interference and lower sidelobes, as a non-CP-OFDM system, FBMC/OQAM achieves the high spectral efficiency [4][5][6][7][8]. And with the development of digital filtering technology, FBMC/OQAM will play a huge role in the next generation communication system.…”

FBMC/OQAM Security Strategy Based on Diversity DNA Encryption

et al. 2021

View full text Add to dashboard Cite

In this paper, a diversity deoxyribonucleic acid (DNA) chaotic encryption strategy is proposed to enhance the physical layer security of the filter bank multi-carrier/offset quadrature amplitude (FBMC/OQAM) system. After the input original binary bit stream is encrypted, it is subjected to FBMC/OQAM modulation. The encryption process of bit data is dynamically controlled by the chaotic sequences generated by the hybrid chaotic system composed of improved-Logistic and delayed tent sine system, which enhances the robustness against malicious attacks by illegal attackers. The diversity DNA encryption strategy expands the key space of the system to 10 180 , which can ensure the physical layer security of the system. The proposed FBMC/OQAM security strategy based on chaotic encryption is transmitted on 25 km standard single mode fiber. Experimental results show that the diversity DNA encryption strategy can effectively ensure the security of transmitted data.
