안테나 라인 디바이스 제어용 적응형 이중 모드 모뎀 설계 및 구현

In this paper, we propose adaptive dual mode modem design technology for Antenna Line Device (ALD) control system of Mobile Communication Base Station(MCBS). The proposed dual mode modem is designed to architecture for a single demodulator that allows demodulation of both OOK and FSK modulated signals operating in different frequency bands using only one ADC. To show the validity of a proposed dual mode modem, we verified with FPGA implementation and the functionality is verified with verification scenario of AISG/3GPP standard.
