Method and device for generating OVSF code words

Method for generating an OVSF code word from code tree index data (i, j) associated with a particular OVSF code within an OVSF code tree,

• where a first code tree index data item (i) indicates the spreading factor SF of the OVSF code, and a second code tree index data item (j) indicates the position of the OVSF code among the OVSF codes having the same spreading factor SF within the OVSF code tree,
• the method having the following steps:
• a) a calculation index is calculated on the basis of the second code tree index data item (j);
• b) the calculated calculation index is buffered as a binary data word having a plurality of data bits;
• c) the data word length N of the calculation index data word is calculated;
• d) the significant data bits of the calculation index data word are interchanged bit by bit in order to form a calculation base B;
• e) the calculation base B is logically combined with a counting variable Z in order to form a logically combined data word;
• f) the logically combined data word is logically reduced in order to generate the OVSF code word.
