“…Instead of other precoding techniques, DST gives better results when combined with μ -law, and the measured PAPR value is 2.88 dB in the FBMC system. The precoding technique can be used to minimize the autocorrelation of the input sequence to decrease the PAPR of the FBMC system and make it efficient (Nissel and Rupp, 2018;Zhao et al, 2018;Kansal et al, 2016Kansal et al, , 2017Kansal et al, , 2018Kansal et al, , 2019Kumar, 2019;Kumar and Rathore, 2019;Srivastava et al, 2020;Agarwal and Sharma, 2020;Kumar and Gupta, 2020;Cheng et al, 2020;Na and Choi, 2019).…”

The filter bank multicarrier (FBMC) system suffers from the non-linear effects that arise due to a high peak-to-average power ratio (PAPR). Diverse precoding techniques are utilized to enhance the efficiency and robustness of FBMC. A high PAPR in the FBMC system can be overcome by a unique combination of precoding and conventional PAPR reduction techniques proposed in this paper. Different precoding schemes, discrete sine transform (DST) and discrete cosine transform (DCT), are combined with different PAPR reduction techniques, such as clipping and companding, to decrease the effects of the elevated PAPR in the FBMC system. The simulation results show a significant reduction in PAPR for both the transforms applied individually as well as in combination with conventional PAPR reduction methodologies. The MATLAB simulation outcome also depicts a substantial reduction in bit error rate (BER) in the range of 5 to 10 dB on the incorporation of DST/DCT precoding transforms in the conventional FBMC system.

SummaryIn wireless telecommunication, one of the modulation approaches used is the orthogonal frequency division multiplexing (OFDM). Moreover, the high peak‐to‐average power ratio (PAPR) is the one notorious demerit in OFDM systems. Hence, the high power amplifier (HPA) is used in its linear region. Otherwise, the bit error rate (BER) will be increased. Several approaches are proposed in the wireless communications for reducing the PAPR issue. In this paper, we propose a hybrid Discrete Hartley Matrix Transform (DHMT) precoding using both selected mapping (SLM) and partial transmit sequence (PTS) PAPR reduction strategies. For the multicarrier modulation process, instead of Inverse Fast Fourier transform (IFFT) operation, the DHMT operation is used because of its low computational complexity. Based on multi‐chaotic, the time‐frequency domain encryption (TFDE) approach is adopted for physical layer security to confirm the security in data transmission. For enhancing the physical layer security, the proposed encryption system generates chaotic sequences based on Logistic maps and Lozi in the frequency and time domains together. In this study, the implementation of the DHMT‐based OFDM system is processed to reduce the maximum PAPR. Implementation is performed on the MATLAB platform, and the performances are calculated using complementary cumulative distribution function (CCDF), BER regards to signal‐to‐noise ratio (SNR), and the outputs are compared based on the computation time. However, compared with the existing models, the proposed model produced better PAPR minimization regarding SNR.
