A contents authoring tool(11) authors contents necessary for a BIFS as a file type according to objects, and sets object editing information in the authored objects. A DMB AV encoder(14) encodes an audio/video source for DMB according to DMB standard. A BIFS encoder(13) generates object identification information for the authored object file according to the objects, maps the generated object identification information to the object editing information, and encodes the corresponding object file according to BIFS standard. A BIFS encoding management unit(12) controls the BIFS encoder by using the object editing information, and transmits the object mapping information set up in the BIFS encoder to a conditional access processing unit(16). An MPEG-2 stream multiplexer(15) multiplexes a TS outputted from the DMB AV encoder and the BIFS encoder. The conditional access processing unit scrambles the stream outputted from the TS multiplexer according to the objects by using the object mapping information according to the request of a user.

Abstract: PURPOSE: An adaptive rake receiving device having at least one restriction in a mobile communication system is provided to estimate each multi-path element channel phase and amplitudes by using an adaptive filter output, thereby removing all multi-user interferences to have channel estimated values without a shit from the adaptive filter output. CONSTITUTION: Transmission delay compensating buffers(100,200) collect parts only occupied by transmission codes of each multi-path element, and transmit the collected parts to adaptive filters(110,210). The adaptive filers(110,210) filter complex receiving signals according to tab weight controlled at predetermined intervals. Channel estimators(130,230) estimate phase elements and amplitude elements of specific user channels. A signal restorer couples channel estimated result signals of the channel estimators(130,230) with a filtered receiving signal applied from the adaptive filters(110,210), and restores to original signals. A selector selects one of the restored signals. A reference signal generator generates a reference signal by using the signal of the selector and the channel estimated result signals. An error calculator calculates an error between the reference signal and the filtered receiving signal. A tap weight controller controls the tab weight on the basis of a constraint MMSE criterion.
