Optimized Multiplicative Pre-Distortion PAPR Reduction Scheme for OTFS Signals by Feiyang Liu, Jiayang Zhao, Guangliang Ren

“…In each iteration, the multiplicative pre-distortion vector is optimized to minimize the introduced in-band distortions before and after the pre-distortion with the preset PAPR constraint using the error vector magnitude (EVM). Simulation results demonstrate that the gain of PAPR reduction in our scheme is about 3.0dB for QPSK and 16-QAM over conventional OTFS signals at the complementary cumulative distribution function level of 10−4 with negligible BER performance degradation and low complexity.…”

Stability Analysis of Isolated Roof in Overlapping Goaf Based on Strength Reduction by Chang Liu, Kui Zhao, Peng Zeng, Cong Gong

“…Focusing on the influence of dislocated width and width ratio on the stability of the isolated roof, this study analyzes the change rule of the safety factor of the roof supported by misaligned pillars and reveals the evolution characteristics of it by integrating numerical simulation into the strength reduction method. Firstly, with the increase of the dislocated width, the safety factor experienced three stages of sharp decrease, change from decrease to increase, and rapid increase. …”

A Review of Partial Transmit Sequence for PAPR Reduction in the OFDM Systems by Yasir Amer Jawhar, Lukman Audah, Montadar Abas Taher, Khairun Nidzam Ramli, Nor Shahida Mohd Shah, Mustafa Musa, Mustafa Sami Ahmed

“…Moreover, the numerical statistic comparison of the current modified-PTS methods is introduced, and the criteria for selecting the suitable modified-PTS method in the OFDM system are also given. The simulation and the numerical calculations results show that the rows exchange-interleaving PTS scheme is the best method for reducing the PAPR value with low complexly in the frequency domain, and the cooperative PTS method is the best among the modulation stage methods, while the cyclic shift sequence PTS method achieves the superior performance in PAPR reduction and computational complexity for the time domain methods.…”

IMPLEMENTATION SIMULATION TECHNOLOGIES IN MEDICAL EDUCATION by Olga Kovalyova

“…Simulation technologies cannot replace the experience gained near the «patient’s bed», but the simulation training provides a number of advantages: the clinical experience gained in the virtual environment does not pose a risk to the patient; objectification of the assessment of the achieved level of skill; unlimited number of repetitions for skills training; practice of rare and life-threatening pathologies; a part of the functions of the teacher takes on a virtual simulator that increases the availability of education; reduction of stress during the first independent manipulations; the training takes place regardless of the schedule of the clinic’s work; development as individual skills and abilities. …”
