Each modulation signal includes a pilot symbol sequence and/or a pilot subcarrier including a plurality of pilot symbols used for demodulation. Each of the pilot symbol sequences and/or pilot subcarriers is inserted at the same temporal point in each modulation signal. The pilot symbol sequences and/or pilot subcarriers are orthogonal to each other, each pilot symbol having a non-zero amplitude. The quantity of the plurality of pilot symbols in each pilot symbol sequence and/or pilot subcarrier is greater than a quantity of the plurality of modulation signals to be transmitted. The plural modulation signals are transmitted from the plurality of antennas in an identical frequency band. Each modulation signal includes different transmission data and one of the pilot symbol sequences and/or pilot subcarriers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and signal generating apparatus for generating modulation signals","description":"A method and apparatus for generating and transmitting modulation signals includes generating a plurality of modulation signals each of which is to be transmitted from a different one of a plurality o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628300","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.
