“…By adopting the FPSO-TR scheme and maximizing HPA efficiency evaluation criteria, the best IBO and MER can be found and the efficiency of HPA would be improved. It can be seen that the overall energy efficiency increases first and then decreases while SNR increases; the energy efficiency reaches the peak value between SNR = [12,17] dB. The energy efficiency increases with the increases of the pilot when pilot ≤ 9%.…”

“…However, due to the low probability of peak value appearance, CCDF improvement does not necessarily imply optimising PA efficiency. Signal peak can be optimization with a variety of approaches and schemes: clipping and filtering (CF) [8]; coding [9]; adaptive symbol selection [10]; partial transmit sequence (PTS) [11] and interleaving [12]; tone reservation/injection [13]; active signal constellation extension (ACE) [14], companding, and so forth [15]. Predistortion and coding schemes are no longer sufficient for modern communication systems; he tone distortion algorithm is considered one of the most potential approaches.…”

Smart Grids (SGs) expedite secure, large-scale and efficient two-way communication between the power supply and management, but under a sophisticated 5G communication infrastructure, the multi carrier system is the principle system. The high peak-to-average power ratio (PAPR) is one of the significant limitations of the 5G multi carrier (MC) system, as it impedes the efficient design of the 5G analogue front end. Tone reservation (TR) is a highly efficient scheme without signal distortion, which is designed by increasing the freedom in the frequency domain for PAPR reduction. In this paper, a particle swarm optimization (PSO) based TR (PSO-TR) scheme proceeding with an optimal input power back off-modulation error ratio (IBO-MER) convergence criterion is proposed to improve high power amplifier (HPA) efficiency for OFDM systems. A probabilistic analysis of TR predistribution and freedom in the frequency domain, in relationship with the amplitude of its constituent samples, is carried out. This yields the theoretical framework employed in design of the proposed high computing-enhanced solutions. The proposed PSO-TR essentially make the frequency domain distribution and operation itself adaptive, that is, it adjusts to comply with the changing HPA efficiency and redundant cost during application runtime.
