  • Time-alignment apparatus and method for time-aligning data frames of a plurality of channels in a telecommunication system
    Patent number: 6771670
    Abstract: In a telecommunication system where data frames of a plurality of channels (CH1,CH2. . . CHn) arrive with respective different time-offsets with respect to a common synchronization clock (WR, R/W, RD, T) of an internal frame structure of a decoder (DEC), three frame memories (RAM1, RAM2, RAM3) are used for performing a time-alignment of the data frames. The data frames are respectively written to two frame memories (RAM1, RAM2) having a read state and a reading of one frame memory (RAM3) is performed beginning with the occurrence of the common synchronization clock (T). A cyclic switching of the read/write state of the frame memories (RAM1, RAM2, RAM3) is performed, such that always two frame memories (RAM1, RAM2) are in a write-state (WR) and one frame memory (RAM3) is in a read-state (RD) The frame memory (RAM3) in the read-state is read out synchronized to the common synchronization clock.
