In long term evolution (LTE) networks, the user equipment (UE) may estimate the power allocation (Pa) parameter by executing a series of steps. For example, the UE may define a single unknown variable from a received downlink MIMO signal, extend the single unknown scalar variable to a multivariate signal model for multiple channels (N), convert the multivariate signal model to a MIMO configured signal model, and then obtain the Pa parameter from the MIMO configured multivariate signal model."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for a scale-invariant symbol demodulator","description":"It is possible to improve the spectral efficiency of multi-layer multiple input multiple output (MIMO) transmissions by estimating the magnitude parameter at the receiver side, rather signaling the ma","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838091","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.
