摘要： The method for selecting the tap of a directory teletext processor (DTP) (11) automatically comprises: (a) calling the error check routine after setting the tap to zero; (b) counting the error by checking the parity and the suffix under the routine; (c) varing the tap from O to seven to check the error; and (d) storing the tap position which includes the minimum error after comparing the checked error numbers of the variation. This routine may be performed at the time of power-on, or during the operation of the teletext.

摘要： PURPOSE: A method for a multicast broadcast service in a wireless communication system and an apparatus thereof are provided to reduce uplink signaling overhead. CONSTITUTION: If an E-MBS(Enhanced Multicast Broadcast Service) channel is changed, a terminal decides whether the changed E-MBS channel is in an effective section(1002,1004). If the changed E-MBS channel is changed in the different channel group, the terminal switches a current carrier to a second carrier(1006,1008). The terminal transmits a report message including an index of the changed group to a serving BS(Base Station)(1010).

A symbol mapping unit(200) maps the channel-coded broadcasting signals by symbols. A multiple switching unit(300) inserts synchronous information into the broadcasting signal. A pilot inserting unit(400) repetitively inserts two pilots into both sides of each symbol of the broadcasting signal, wherein the two pilots have different voltages. A modulating unit(500) executes offset-QAM(Quadrature Amplitude Modulation) to each symbol of the broadcasting signal. A shaping filter(600) filters the symbols of the broadcasting signal. An RF(Radio Frequency) amplifying unit(700) amplifies the high frequency broadcasting signal.

摘要： PURPOSE: A carrier restoring system of a digital broadcasting receiver for stably restoring carriers using two pilots is provided to perform stable restoration of carriers even when a pilot is damaged due to a variation in channel environment. CONSTITUTION: A carrier restoring system of a digital broadcasting receiver includes a plurality of frequency offset assumption units(120,140), a combining unit(160), a phase offset assumption unit(170), and a voltage-controlled oscillator(180). Each of the plurality of frequency offset assumption unit shifts a plurality of pilot tones included in I-signal and Q-signal of a digital broadcasting signal to a baseband to assume a frequency offset value of a carrier, generated when the digital broadcasting signal is tuned. The combining unit combines frequency offset values assumed by the plurality of frequency offset assumption units. The phase offset assumption unit assumes a phase offset value of the carrier. The voltage-controlled oscillator compensates for the frequency offset value and the phase offset value to oscillate a voltage with a predetermined level for carrying out tuning.

摘要： PURPOSE: A 256-quadrature amplitude modulation(QAM) branch metric circuit for a trellis coded modulator(TCM) decoder is provided to implement an in-phase(I) branch metric circuit so as to find the first to the fourth branch metrics. CONSTITUTION: An in-phase(I) branch metric circuit comprises as follows. A first adder(210) adds each of I signals of a 256-QAM and each of 256-quadrature amplitude modulation(QAM) constellation values. An absolute value circuit(220) makes each of the added first to sixteenth values absolute values. A comparison selector(230) reciprocally compares the first to the sixteenth values, and selects a first and a second minimal value. First/second registers(240,250) store the first and the second minimal value. A second adder(260) reciprocally adds the first/the second minimal values from the comparison selector(230) to the first/the second minimal values from the first/the second registers(240,250). A multiplexer(270) responds to a control signal from an exterior, and selects four signals among seventeenth to twentieth added values and the first/the second minimal values from the second adder(260), then generates first to fourth I branch metrics.
