The reference symbols are known at the receiver. The receiver removes the reference symbols from the linear transformation signal and decodes the data-bearing pre-coding transform."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"LPI/LPD communication systems","description":"In a wireless communication system, a secure communication link is provided by producing a set of reference symbols selected from a modulation symbol constellation; generating a data-bearing pre-codin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11277392","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.
