전파 및 채널 모델
RF 경로 전파 모델링은 신호(전자기파)가 송신 지점에서 시작하여 주변 환경을 통해 전파될 때의 전자기 복사 동작을 나타냅니다. RF 전파 경로를 모델링하고 3차원으로 시각화합니다.
채널 모델링은 통신 시스템 링크의 무선 환경을 기술합니다. 전파 분석 및 채널 모델링은 다양한 시나리오에서 어떻게 송신기에서 수신기까지 전자파의 손실이 발생하는지 이해하는 데 필수적입니다. 레일리, 라이시안 또는 WINNER II 페이딩 프로파일을 가진 잡음 있는 SISO 및 MIMO 채널을 모델링하고 시각화합니다. 대기에서의 손상 및 다중 도플러 스펙트럼 형상도 사용할 수 있습니다.
