The over-sampler is connected to a de-interleaver configured to divide the time-domain channel estimate into m de-interleaved sub-vectors. The de-interleaver is connected to a suppressor configured to suppress noisy taps from each de-interleaved sub-vectors to form m noise suppressed sub-vectors. The suppressor is connected to a selector configured to select a noise suppressed sub-vector associated with a highest signal-to-noise ratio. The selector is connected to a discrete Fourier transformer configured to transform the selected noise suppressed sub-vector into a noise suppressed preliminary frequency-domain channel estimate. The discrete Fourier transformer is connected to a phase-shifter configured to phase-adjust the taps of the noise suppressed preliminary frequency-domain channel estimate to form an enhanced frequency-domain channel estimate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for enhancing channel estimation","description":"A noisy frequency-domain channel estimate enhancer includes an over-sampler configured to transform the noisy frequency-domain channel estimate into a time-domain channel estimate that is virtually ov","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462904","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.
