Channel oriented noise shaping

Methods, systems, and devices for wireless communications are described. A transmitting device may determine channel quality, and may shape frequency domain noise (e.g., crest factor reduction (CFR) related noise) to locations in which channel quality is poor. For example, by shaping channel noise to frequency resources with poor channel quality (e.g., instead of uniformly distributing such channel noise), transmissions may be more reliable, and quality on other frequency resources may be improved (e.g., without negatively impacting the quality of communications via frequency resources that already have a low channel quality), resulting in improved dynamic range of the signal (e.g., peak to average power ratio (PAPR)), which means that power efficiency is improved.
