The receiver includes a down-converter configured to convert an input signal containing the primary and secondary signals, to a baseband complex symbol stream, A first processing unit processes the baseband complex symbol stream and provides a primary bitstream transmitted by the primary signal or a decoded primary log-likelihood ratio stream. A symbol reconstructing unit is configured to process the primary bitstream or the decoded primary log-likelihood ratio stream and to provide a reconstructed primary symbol stream. A subtraction unit is configured to provide a difference symbol stream by substracting the baseband complex symbol stream and the reconstructed primary symbol stream from each other. A second processing unit is provided to process the difference symbol stream and to provide the secondary bitstream transmitted by the secondary signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Receiver","description":"A receiver is provided to receive a secondary bitstream which is transmitted by a secondary signal together with a primary signal.
