Abstract
The invention relates to a converter (CVT) and a conversion method for converting an input data packet stream (IDPS) of consecutive data packets (DP , DP , DP . . . DP ) each data packet including user (US , US , US , . . . US ) data in the form of a predetermined number (Nsymbol ; Nsymbol ; Nsymbol ) of consecutive data symbols (S ( ), S ( ) . . . S (Nsymbol −1); S ( ), S ( ) . . . S (Nsymbol −1); S ( ), S ( ) . . . S (Nsymbol −1); . . . S ( ), S ( ) . . . S (Nsymbol −1)) from a plurality of N user channels (ch- , . . . ,ch-N−1), each user channel having a predetermined transmission rate TR , TR , TR , . . . ,TR , . . . TR , being defined as a basic transmission rate TR or an integer multiple TR =K *TR thereof, into an output data symbol stream (ODSS) in which a respective number K of data symbols (S ( ); S ( ), S ( ), S ( ), S ( ); S ( ); . . . S ( ), S ( )) of each data packet are sequentially arranged. The write means (W) writes the data symbols into a memory (M) in the row direction in a specific order and a read means (R) reads the memory (M) in the column direction. Thus, independent of the transmission rate (TRB) of the individual user channels, a CDMA-modulator (MOD) can be provided respectively with the first data symbol or a set of first data symbols from each packet within a predetermined time interval (1/TR ).
