Improved SLM technique with a new phase factor for PAPR reduction over OFDM signals

Interference Management Based on Meta-Heuristic Algorithms in 5G Device-to-Device Communications

“…Over the past decade, there has been a significant increase in the number of mobile users, resulting in a substantial burden on the cellular network core [1,2]. To keep pace with advancements in cellular networks, extensive research is being conducted to drive the evolution toward the next generation of cellular networks, commonly referred to as the fifth generation (5G) and beyond (5GB) [3,4]. These technologies aim to alleviate network strain, improve energy and spectral efficiency, reduce latency, and increase throughput.…”

Utilization of Compressed Sampling for PAPR Reduction in OFDM IEEE-802.11a System

“…In [8], a modified Hadamard-based SLM algorithm is proposed to overcome the transmitting of SI requirement in typical Hadamard-based PTS technique; which reduces the bandwidth efficiency. B. Lekouaghet et al in [9] applied normalized Riemann matrix (RM) rows and a modified RM diagonal elements, along with rows of the symmetric Toeplitz matrix, as phase sequences for SLM strategy to reduce the PAPR in OFMD system. Partial Transmit Sequence (PTS) is another effective scheme for PAPR reduction hat is partially transmitting the OFDM symbols as clusters with different phase rotations.…”
