PURPOSE: An apparatus and a method for offering the position information, an apparatus and a method for displaying the position of a vehicle using a digital audio broadcasting(DAB) are provided to DAB broadcast in real time by calculating the error value of the positional coordinate. CONSTITUTION: An apparatus for offering the positional information includes a global positioning system(GPS) receiver(200), a positional coordinate calculation unit(241), an error value detection unit(243) and a broadcast transmission unit(210). For example, In a local radio station the GPS receiver(200) receives PSN from the GPS satellite. The geographic coordinate calculation unit(241) computes the pseudoranges with the PSN signal. The error value detection unit(243) detects the error value by comparing the coordinate calculated by the position coordinate calculation unit(241) with the real coordinate of the local radio station. And, the broadcast transmission unit(210) broadcasts the error valued detected by the error value detection unit(243).

PURPOSE: An advertising method using a game network is provided to supply a game machine at low price by executing an advertisement of a specific company using a conventional network game machine, thereby guaranteeing a predetermined profit to a game machine manufacturer. CONSTITUTION: Each participating network game machine selects a master or a slave(701). A game is started through time control modules of a master network game machine and an interrupt is waited(702). If an interrupt is received(703), the progressed game is temporarily stopped(704). It is judged whether the interrupt informs that a predetermined stage of the game is completed(705). If the interrupt is a game stage termination interrupt, one stage termination of the game is informed and an advertisement starting and progressing time are set(707). The master game machine transmits a predetermined message for instructing a progress of an advertisement to other slave game machines based on the above processing result(708). The master game machine displays a corresponding advertisement on a monitor thereof(709). The game is restarted(710).

PURPOSE: An improved method for estimating a frequency offset of a mobile communication system is provided to obtain a diversity gain and improve the accuracy of the frequency estimation by combining estimated values of each frequency offset. CONSTITUTION: An estimating process of frequency offset is performed in each sub channel, respectively. A frequency offset combination process is performed to combine the estimated values of each frequency offset. A mobile communication system is formed with a multi-input/output channel modulation system, a transmission diversity system, a multi-code division multi-access system or a binary code division multi-access system. The multi input/output channel modulation system or transmission diversity system perform a frequency offset estimation process by using a predetermined mathematical expression.

PURPOSE: A device for generating an accord in a network toy using a wireless communication and a method thereof are provided to activate an education by creating an accord using a network doll and toy, thereby increasing competitive powers of children. CONSTITUTION: If users operate terminals and constitute a network(S300), it is checked whether each terminal is connected(S301). An education or a game is started(S303). In the case that a game is started, the user controls a switch of the terminal for playing the game. After playing the network game, a winner is decided(S304), and a terminal of the winner is designated as the master terminal(S305). A controller of the master terminal constitutes a network based on the master among slave terminals according as the user inputs the switch(S306) and selects a music and an accord according as the user inputs the switch(S307). If a music is selected, the slave terminals generate each accord in accordance with a control signal of the master terminal, and a chorus is progressed(S308). If the music is terminated, the controller of the master terminal releases the constitution of the network(S310).
