To improve the speed of global optimization algorithm, a class of global optimization algorithms for intelligent electromechanical control system with improved filling function is proposed. By attaching the intelligent managing system improving algorithm and the filling function procedure, the algorithm can stand out from the current particular optimal solution, avoid the phenomenon of falling into the local favorable solution in the process of algorithm iteration, make the algorithm find a better solution, and improve the efficiency of solving the multiextremum global improving problem. Multiextremum-seeking is an optimal control technique that works with unknown conditions while assuming that measurements of the plant’s input and output signals are accessible. The presented work is for an electromechanical system which will handle the low accuracy and untimely tendency of conventional systems which are used in various practical applications. Few learning algorithms have been developed to explicitly optimize mean average precision (MAP) due to computational constraints. The outcomes show that the convergence of the test functions F6 and F7 is not good when the MAPID algorithm is only used for optimization. The MAPID_FF algorithm not only ensures the convergence and optimization precision of the two test functions, but also reduces the optimization time compared with the filling function method. Compared with the filling function method, the improved algorithm has higher accuracy and faster speed, and it is not simple to fall into the local optimum, so the global optimal value is more accurate.

“…Besides, it also reduces both out-of-band (OOB) radiation and inter-symbol interference (ISI) 16 . Similary to other multicarrier schemes, a high peak-to-average power-ratio (PAPR) is the main issue in the GFDM system 17 . This causes a non -linear distortion that increases energy consumption in the transmitter power amplifier.…”

Several techniques have been used to tackle the PAPR problem in Generalized Frequency Division Multiplexing (GFDM) systems. The Selective mapping (SLM) remains the most used alone or in combination with optimization algorithms in order to find optimal phase factors. Unfortunately, the complexity of implementation and the use of many control parameters are the main drawbacks of these techniques. This paper proposes an enhanced SLM technique to further improve the PAPR reduction in the GFDM system without increasing the system complexity. The proposed technique, i.e., JAYA-SLM, combines the JAYA algorithm with the SLM scheme. The simulation results demonstrate that the proposed JAYA-SLM technique is highly efficient in PAPR reduction without increasing the system complexity, wherein fewer used parameters. Also, it improves the system’s power saving and the Bit-Error-Rate (BER) performance when compared to others existing methods.

“…OFDM has also been used to transmit chaotic-based encrypted audio signal and used multi-carrier chaotic Communication (Chen et al, 2019;El-Zoghdy et al, 2020). Generalized frequency division multiplexing (GFDM) is a multi-carrier method for the secure transmission of data for the next generation communication band, 5G (Kumar et al, 2021). Another usage area of GFDM is for underwater systems to communicate with each other.…”

Data security is very crucial for communication systems. Encryption methods are frequently used to ensure the security. Chaotic oscillators are used for encryption of data because they produce signals that do not repeat themselves. Identical chaotic oscillators should be used and synchronized with each other in order to perform encryption and decryption processes in a healthy way. In this study, the encrypted data and synchronization signal are transmitted to the receiver side using frequency division multiplexing (FDM) method to realize the synchronization between two chaotic oscillators. High-frequency keying is used to increase the encryption quality of the signal to be encrypted on the transmitter side. Proportional-Integral-Derivative (PID) control is used to provide synchronization between two chaotic oscillators. Correlation test, peak signal to noise ratio (PSNR), mean square error (MSE) and spectral entropy were used to determine the accuracy relationship between the original signal and the decryption signal. As a result, the encryption success and reliability of the created system were verified by simulation programs and numerical analysis.
