Crest factor 1 indicates no peaks, such as direct current or a square wave.
This is because: Orthogonal frequency-division multiplexing (OFDM) is a very promising modulation technique; perhaps its biggest problem is its high crest factor.
[14][15] Many crest factor reduction techniques (CFR) have been proposed for OFDM.
Over the years, numerous model-driven approaches have been proposed to reduce the PAPR in communication systems.
In recent years, there has been a growing interest in exploring data-driven models for PAPR reduction as part of ongoing research in end-to-end communication networks.
These data-driven models offer innovative solutions and new avenues of exploration to address the challenges posed by high PAPR effectively.
By leveraging data-driven techniques, researchers aim to enhance the performance and efficiency of communication networks by optimizing power utilization.
