A transmitting device and a receiving device determine a perturbed precoding matrix based on a precoding perturbation rule. The transmitting device precodes a signal using the perturbed precoding matrix and transmits via the number of antennas greater than the number of spatial streams. The receiving device receives the signal and subtracts non-linearities from the received signal based on a channel estimation using the perturbed precoding matrix over one or more iterations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Precoding perturbation to allow large array digital post distortion","description":"This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for performing wireless communication using digital post distortion, for example","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11956006","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.
