“…Seung-Chan Lim, Namshik Kim, and Hyuncheol Park [20] proposed a polar coding-dependent SLM technique for PAPR decrease deprived of communicating controller moments. The proposed SLM verifiably takes advantage of free and consistently appropriated frozen information squares to specifically send the OFDM signal with the most minimal PAPR.…”

The hybrid innovation of Orthogonal Frequency Division Multiplexing (OFDM) through Multiple-Input Multiple-Output (MIMO) delivers a feasible substitute to increase the Quality of Service (QoS) to accomplish better data rate and spectral efficiency for the transmission network. An extraordinary Peak-to-Average Power Ratio (PAPR) and Bit Error Rate (BER) are the important parameters that can be considered in the analysis of the MIMO-OFDM network. Partition Transmit Sequences (PTSs) is one of the capable procedures and direct methods to attain a reasonable PAPR performance. However, it needs a serious restoration process to discover the vital features that produce a computational multi-layered design with sub-blocks. Here, a reduced computational complexity PTS scheme is proposed which is completely depends on the hybrid procedure named as Moth Flame Optimization with Improved Firefly Algorithm (MFO-IFFA). The simulation outcomes demonstrated the capability of the proposed MFO-IFFA approach decreases the PAPR reduction up to 3.6 dB. Similarly, the proposed MFO-IFFA overcomes the significant evolutionary procedures mentioned in the existing works such as Additive Signal Mixing (ASM), Adaptive Simplified Optimized Iterative Clipping and Filtering (ASOICF) and Hybrid Independent Component Analysis (HICA).

“…High complexity is another significant downside for the chosen SLM and PTS approaches as a result of them being the best choice among many phase sequences. SI-free approaches fall under another category of PAPR reduction techniques [8][9][10][11][12]. In [8], the PAPR was decreased by physically clipping the transmitted signal, albeit at the expense of the bit error rate (BER) and out-of-band radiation performance degradation.…”

In this paper, a new peak average power and time reduction (PAPTR) based on the adaptive genetic algorithm (AGA) strategy is used in order to improve both the time reduction and PAPR value reduction for the SLM OFDM and the conventional genetic algorithm (GA) SLM-OFDM. The simulation results demonstrate that the recommended AGA technique reduces PAPR by about 3.87 dB in comparison to SLM-OFDM. Comparing the suggested AGA SLM-OFDM to the traditional GA SLM-OFDM using the same settings, a significant learning time reduction of roughly 95.56% is achieved. The PAPR of the proposed AGA SLM-OFDM is enhanced by around 3.87 dB in comparison to traditional OFDM. Also, the PAPR of the proposed AGA SLM-OFDM is roughly 0.12 dB worse than that of the conventional GA SLM-OFDM.

“…In addition, high complexity is another main drawback for the selected SLM and PTS methods due to the optimal selection from multiple phase sequences. Another category of PAPR reduction methods [6][7][8][9][10] is SI-free approaches. In [6], the PAPR was reduced by directly clipping the transmitted signal, at the cost of degrading the performances of bit error rate (BER) and out-of-band radiation.…”

“…In [8], an extended SLM was proposed for the PAPR reduction without SI by constructing extension matrices comprising amplitude extensions and phase rotations. In [9], a polar codingbased SI-free SLM scheme was presented by constructing coset codes of a linear polar code, and meanwhile, an adaptive trialbased blind receiver was presented for detection of the selected signal. In [10], the authors proposed a blind interleaving technique with signal space diversity, which reduces the PAPR in OFDM significantly without the need of SI.…”

For existing orthogonal frequency division multiplexing (OFDM) in 5G internet of things (5G-IoT) systems, one of the critical problems is the high peak to average power ratio (PAPR), which seriously degrades the energy efficiency. To this end, we propose a novel modulation technique with low PAPR for IoT systems, which preserves the advantage of low implementation complexity and ability to fight against multipath channels. The key methodology is the employment of symbol repetition in the frequency domain. Hence, by designing the appropriate phase factors on the repeated symbols, the PAPR of transmitted signals is equivalent to that of an OFDM signal with a reduced size of discrete Fourier transform (DFT). It is demonstrated that, even if there exists repetitive symbols, the proposed method can still maintain an unreduced spectral efficiency performance. Moreover, to evaluate the proposed method, the Monte-Carlo simulations are conducted for the complementary cumulative distribution function (CCDF) and the bit error rate under multipath fading channels. The simulations show that, as CCDF = 10 − 3 , the proposed method can achieve 2.5 dB gains about the PAPR compared with the original OFDM signal.
