A target feedback antenna of the transmitter is configured to receive, under control of the processor, a first mixed signal obtained by superimposing the m training signals in space, where a phase difference between the first mixed signal and a second mixed signal obtained by superimposing in space the m training signals received by a receiver device falls within a preset range. A processor of the transmitter is configured to: perform DPD parameter estimation and pre-distortion processing on a to-be-sent signal. The m transmit antenna groups are further configured to send, under control of the processor, the to-be-sent signal on which pre-distortion processing has been performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmitter device and signal processing method","description":"This application relates to the field of communications technologies and discloses a transmitter device and a signal processing method. m transmit antenna groups of the transmitter are configured to s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11239870","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.
