“…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.

“…Multiple PAPR reduction techniques have been introduced to reduce the probability of operating in the nonlinear domain such as clipping and filtering [2], interleaving [3], partial transmit sequence (PTS) [4], Tone reservation (TR) [5] and active constellation extension (ACE) [6]. When employing any of these techniques, it is important to examine whether they impair the transmission quality by introducing distortions, reducing the data rate, increasing the bit-error ratio (BER) or the necessary transmit power or call for additional information to be transmitted along the data.…”

“…Additionally, a hybrid of data-aided and blind methods has been recently advised [8], which is referred to as the semiblind approach. For example, blind methods which use the orthogonality between null subcarriers, which are referred to zero padding [9], [10], are used in the transmitted OFDM symbols and the information-bearing subcarriers (see in [11], [12]). In [13], redundant information in the cyclic prefix (CP) before the OFDM symbols made possible estimation without additional pilots, joint symbol timing.…”
