Abstract:
1. A detection unit for the detection of data symbols in a demodulated signal, whereby band spreading occurs transmit-side with the use of first sequences whose first chips each assume one of two different first values, the detection unit comprising: a sequence providing unit for providing a group of second sequences with at least one second chip, each second sequence being assigned to a first sequence and each second chip assuming a specific value of at least two different second values, which differ from the first values, the group having at least one second sequence that has a higher level than the first sequences; a correlation unit connected to the sequence providing unit for calculating correlation results by correlating the demodulated signal with each second sequence of the group; and an evaluation unit connected to the correlation unit for deriving values of the data symbols by evaluating the correlation results, wherein each second chip assumes one specific value of at least two different second values, which each correspond in value to an integer positive power of two (2
