ENCODER, DECODER AND METHODS FOR ENCODING AND DECODING DATA SEGMENTS REPRESENTING A TIME-DOMAIN DATA STREAM

摘要

AN APPARATUS (100) FOR DECODING DATA SEGMENTS REPRESENTING A TIME-DOMAIN DATA STREAM, AS DATA SEGMENT BEING ENCODED IN THE TIME DOMAIN OR IN THE FREQUENCY DOMAIN, A DATA SEGMENT BEING ENCODED IN THE FREQUENCY DOMAIN HAVING SUCCESSIVE BLOCKS OF DATA REPRESENTING SUCCESSIVE AND OVERLAPPING BLOCKS OF TIME-DOMAIN DATA SAMPLES. THE APPARATUS COMPRISES A TIME-DOMAIN DECODER (110) FOR DECODING A DATA SEGMENT BEING ENCODED IN THE TIME DOMAIN AND A PROCESSOR (120) FOR PROCESSING THE DATA SEGMENT BEING ENCODED IN THE FREQUENCY DOMAIN AND OUTPUT DATA OF THE TIME-DOMAIN DECODER TO OBTAIN OVERLAPPING TIME-DOMAIN DATA BLOCKS. THE APPARATUS FURTHER COMPRISES AN OVERLAP/ADD-COMBINER (130) FOR COMBINING THE OVERLAPPING TIME-DOMAIN DATA BLOCKS TO OBTAIN A DECODED DATA SEGMENT OF THE TIME-DOMAIN DATA STREAM.
