와이브로 시스템을 위한 상하향 변환 모듈의 FPGA 설계 및 구현

In this paper, we implement the UDCM(Up Down Conversion Module) in the WiBro RAS(Radio Access Station) system which provides important interface between a channel card and Radio Equipment(RE). It is implemented on a FPGA (Field Programmable Gate Array). UDCM performs an up and down conversion of 10Mhz intermediate frequency and filters the spurious within channel band. Its operation is verified by connecting to a channel card or a radio unit after the whole process of synthesis, PAR(Place and Route) and bit flash generation then we completed UDCM in the WiBro RAS.
