The communication system also includes a processor to determine a minimum mean squared error (MMSE) matrix based on the set of spreading codes and a variance of noise in the channels, project the MMSE matrix to a low-dimensional space to produce a low-dimensional MMSE matrix, update the set of coefficients of set of correlators with the elements of the low-dimensional MMSE matrix, and update elements of a dictionary matrix based on the elements of the low-dimensional MMSE matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Symbol detection in shared wireless channel","description":"A communication system includes a receiver to receive a signal with symbols encoded with a spreading code selected from a set of spreading codes, a filter to produce a filtered signal using a number o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10498558","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.
