    • A mobile RFID(Radio Frequency IDentification) service agent device for vicariously processing RFID information of a mobile terminal and a method thereof are provided to reduce power consumption and a communication charge by minimizing network communication/operation of the mobile terminal, as a mobile RFID service agent vicariously processes the operation needed for using an RFID network service. A command interpreter(420) extracts a command and a parameter by parsing a command message received from the mobile terminal. A task processor(440) extracts and performs a related task module from a record corresponding to a task name which is one of the parameter in case that the extracted command is 'RunTask'. A response transmitter(470) transmits a performance result message of the task processor to the mobile terminal. The task processor registers the record corresponding to the task name in the case that the extracted command is 'AddTask', and updates or deletes the record corresponding to the task name in the case that the extracted command is 'UpdateTask' or 'DeleteTask'.

    • A device and a method for FFT(Fast Fourier Transform) are provided to offer a simple binary reverse output order, reduce complexity, and minimize the number of hardware elements by using a structure formed with only the adders without any multiplier, as a mixed radix 4-2 butterfly structure is used. The first butterfly operation module(130) generates four first output data by performing a radix-4 butterfly operation from input data and data received from the first feedback memory(120). The first multiplexer(140) outputs the data from the first feedback memory or the first output data to the first output port. The second multiplexer(150) stores the input data or the data excluding the data output from the first multiplexer among the first output data. A controller(190) makes the first and second multiplexer provide the first output data to the first output part according to the simple binary reverse output order.

    • An OFDMA-TDD(Orthogonal Frequency Division Multiplexing Access-Time Division Duplexing) system and a method for setting a packet transmission correcting time are provided to set a correction time based on the delay time of ranging packets received in a base station modem, and the symbol time and guard time of the OFDMA-TDD system and transmit the correction time to a mobile station. A method for setting a packet transmission correcting time comprises the following steps of: confirming whether ranging is requested or not by enabling a base station to receive a message from a mobile station in a standby state(S401,S402); confirming a ranging packet arrival delay time on the basis of the received message if there is the ranging request(S403); calculating a deviation time by using the guard time of a symbol previously specified and the confirmed delay time(S404); setting a correction time for correcting the point of time for the packet transmission of the mobile station on the basis of the calculated deviation time(S405,S406,S407); and returning to the standby state after transmitting a ranging response message including correction time information to the mobile station(S408).
