초록

In a telecommunication system where data frames of a plurality of channels (CH 1 ,CH 2 . . . 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 (RAM 1 , RAM 2 , RAM 3 ) are used for performing a time-alignment of the data frames. The data frames are respectively written to two frame memories (RAM 1 , RAM 2 ) having a read state and a reading of one frame memory (RAM 3 ) is performed beginning with the occurrence of the c...

청구항

1. A time-alignment apparatus of a receiver of a telecommunication system for receiving successive data frames on a plurality of channels, wherein said respective data frames on said channels are not time-aligned, and for outputting said data frames of all channels time-aligned to a common synchronisation clock, comprising:a) at least a first, second and third read/write frame memory for respectively storing one data frame of each of said channels, said frame memories each having a write state in which data is written to said frame memories by an input m...
