Abstract
Methods, systems, and devices for wireless communications are described. A transmitting device or a receiving device may indicate support for crest factor reduction (CFR) techniques using clipping and mirroring. The transmitting device may indicate a clipping level and a mirroring level for a CFR function. The transmitting device may generate a waveform in accordance with the CFR function and may transmit the waveform to the receiving device. The receiving device may monitor the waveform to detect one or more mirrored portions of the waveform. The receiving device may invert the one or more mirrored portions of the waveform over the mirroring level to restore and decode the waveform.
