When efforts are taken to reduce memory effects, such as configuring a network of components (138) that couple to an HPA (114) to avoid resonance frequencies within a video bandwidth (140), high performance linearization at low power results without extending linearization beyond that provided by the memoryless nonlinear predistorter (58). Each nonlinearity is addressed by applying gain to a communication signal (54). The amount of gain applied is determined by a look-up table (170) for one nonlinearity (146) and by a look-up table (198) in combination with a differentiator (202) for the other nonlinearity (148). The look-up tables (170, 198) are updated in accordance with modified LMS control loops."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmitter linearized using bias deviation gain adjustment and method therefor","description":"A transmitter (50) includes a low power memoryless nonlinear predistorter (58) that inserts predistortion configured to address a nonlinearity (146) corresponding to gain droop and another nonlinearit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8489047","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.
