MULTI-CARRIER INTERFACE DEVICE USING DIGITAL ELEMENTS IN MOBILE COMMUNICATION SYSTEM

PURPOSE: A multi-carrier interface device using digital elements in a mobile communication system is provided to intensively compose elements applied to a circuit and enhance the stability and reliability of a system by processing a 3FAs(Frequency Assignments) analog IF(Intermediate Frequency) signal using the digital elements by a multi-carrier type. CONSTITUTION: An I-channel analog/digital converter(100) receives a plurality of analog IF signals and converts the received analog IF signals into digital IF signals. A Q-channel analog/digital converter(100) receives a plurality of analog IF signals and converts the received analog IF signals into digital IF signals. A plurality of digital signal control units(200) receive the digital IF signals from the I-channel analog/digital converter(100) and the Q-channel analog/digital converter(100), synchronize the received digital IF signals, filter only specific band, extract information signals, and transmit the extracted information signals. A data format converting unit(300) receives the information signals from a plurality of digital signal control units(200) in parallel, reallocates the received information signals as information signals with a serial type, and transmits the reallocated information signals.
