The QAM-based, ISC signal may be a partial response signal generated by passing a first signal through a partial response pulse shaping filter. The partial response pulse shaping filter may provide greater capacity than a capacity achieved by passing the first signal through a root-raised-cosine-based pulse shaping filter. The receiver may comprises an input filter, and the processing of the QAM-based, ISC signal may comprises filtering the QAM-based, ISC signal via a filter configured to achieve a desired total partial response in combination with the partial response pulse shaping filter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Highly-spectrally-efficient receiver","description":"A receiver may be operable to receive a QAM-based, inter-symbol correlated (ISC) signal at a signal-to-noise ratio of between 29 dB and 31 dB and process the QAM-based, ISC signal to output estimated ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526523","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.
