초록

복잡하고 다양한 전파 환경을 라이시안 채널로 모델링할 수 있는 가능성에 대해서 검토해 보았다. 라이시안 채널에서의 수신 신호를 컴퓨터 시뮬레이터를 제작하여 모의 실험하였고, 모의 실험된 신호의 PDF(포락선 크기의 분포), PSD(Power Spectral Density), LCR(Level Crossing Rate), ADF(Average Duration of Fades), BER(Bit Error Rate)를 이론치와 비교한 결과 매우 잘 일치함을 확인할 수 있었다.

The possibility of modeling the complex and diversified radio environment using Rician channel has been considered. The signals received in Rician channel have been simulated using the computer simulator. The PDF(Probability Density Function of the Envelope amplitude), PSD(Power Spectral Density), LCR(Level Crossing Rate), ADF(Average Duration of Fades) and BER(Bit Error Rate) of the simulated signal have been compared with those of theory. They were shown to be in good agreement.
