The invention relates to a converter (CVT) and a conversion method for converting an input data packet stream (IDPS) of consecutive data packets (DP0,0,DP1,0,DP2,0. . . DPN-1,0) each data packet including user (US0,US1,US2,. . . USN-1) data in the form of a predetermined number (Nsymbol0; Nsymbol1;

The invention relates to a converter (CVT) and a conversion method for converting an input data packet stream (IDPS) of consecutive data packets (DP0,0,DP1,0,DP2,0. . . DPN-1,0) each data packet including user (US0,US1,US2,. . . USN-1) data in the form of a predetermined number (Nsymbol0; Nsymbol1; NsymbolN-1) of consecutive data symbols (S0,0(0), S0,0(1) . . . S0,0(Nsymbol0-1); S1,0(0), S1,0(1) . . . S0,0(Nsymbol0-1); S2,0(0), S2,0(1) . . . S2,0(Nsymbol2-1); . . . SN-1,0(0), SN-1,0(1) . . . SN-1,0(NsymbolN-1-1)) from a plurality of N user channels (ch-0, . . . ,ch-N-1), each user channel having a predetermined transmission rate TR0,TR1,TR2,. . . ,TRn,. . . TRN-1,being defined as a basic transmission rate TRBor an integer multiple TRn=Kn*TRBthereof, into an output data symbol stream (ODSS) in which a respective number Knof data symbols (S0,0(0); S1,0(0), S1,0(1), S1,0(2), S1,0(3); S2,0(0); . . . SN-1,0(0), SN-1,0(1)) 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/TRB).
