The data symbol vector corresponds to a transmitted data symbol vector comprising a corresponding plurality of transmitted data symbols. Data values are estimated for transmitted data symbols in a first group of transmitted data symbols using a hard-decision technique. One or more iterations of refining estimated data values for at least one of the transmitted data symbols in the first group are performed based on estimated data values for the other one or more transmitted data symbols in the first group. Likelihood values for bits corresponding to transmitted data symbols in a second group of transmitted data symbols are calculated using a soft maximum-likelihood (ML) technique based on the estimated and refined data values of transmitted data symbols in the first group."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-stream demodulation schemes with progressive optimization","description":"A data symbol vector comprising a plurality of data symbols is received.
