Abstract
The invention relates to a time-alignment apparatus and a time-alignment method of a transmitter (TX) of a telecommunication system TELE. Successive data frames (ch , ch , ch , ch , ch , ch ) are written to one or two frame memories (RAM , RAM ) starting at a respective frame start write address (FRST-ADR ). A third frame memory (RAM ) having a read state is read out in the column direction such that one data symbol of each storage resource (RES , RES . . . RES ) can be output to a modulator unit (BBTX) of the transmitter (TX). The read-write state (WR/RD) of the three frame memories (RAM , RAM , RAM ) is cyclically switched through a first lo third alignment mode (M , M , M ) such that always a first write state memory (RAM ) and a second write state memory (RAM ) are provided.
