The circuitry of the sequence estimation circuit is operable to generate, based on the corrected soft bit decisions, second soft bit decisions for the symbols of the received inter-symbol-correlated signal, which are improved/refined relative to the first soft bit decisions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reception of inter-symbol-correlated signals using symbol-by-symbol soft-output demodulator","description":"A receiver comprises a sequence estimation circuit and a soft-input-soft-output (SISO) decoder.
