The third group for each first pseudo noise (PN) sequence has a derived sequence assigned to the first PN sequence. The detection unit includes a correlation unit, which is connected to the sequence providing unit and formed to calculate correlation results by correlating the differentially demodulated signal with each derived sequence of the third group. The detection unit includes an evaluation unit, which is connected to the correlation unit and is formed to derive the values of the data symbols by evaluating the correlation results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential detection a communication system","description":"In one embodiment, a detection unit includes a sequence providing unit to provide a third group of derived sequences.
