In one aspect of the disclosure, an apparatus is provided. The apparatus comprises an interference computation unit configured to compute a combined interference based on detected user symbols for a first spreading factor and detected user symbols for a second spreading factor, wherein the combined interference accounts for multi-user interference from user symbols for the first and second spreading factors. The apparatus further comprises an interference cancellation unit configured to remove the computed combined interference from a plurality of received symbols corresponding to the first spreading factor and a redetection unit configured to redetect the user symbols for the first spreading factor from the plurality of received symbols with the computed combined interference removed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for multi-user detection in the presence of multiple spreading factors","description":"Methods and systems for multi-user detection in the presence of multiple spreading factors are provided.
