The crest factor of the original waveform may be reduced based on spectral mask requirements. The generating of the conditioned waveform may be iterated. The distortion signal may be generated based on a predistortion model. A signal may be fed back from an output of the PGA to the predistortion model, which may be dynamically configured."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for crest factor reduction","description":"Methods and systems for crest factor reduction may comprise generating an original waveform to be amplified by a programmable gain amplifier (PGA); generating a distortion signal utilizing a PGA model","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705541","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
