Abstract

It is very important to simulate various mobile communication channels for the reliable system design and performance tests. Therefore, a new method is proposed in this paper to improve the conventional one for the purpose of the efficient channel simulation having various characteristics. A newly proposed method can simulate any narrow band channel very efficiently from the given Doppler power spectrum model. Also, it has many simulation advantages considering the variety of wireless channel conditions since parameters related with channel characteristics, such as a signal power, signal to noise ratio, direct signal power ratio, etc., can be easily changed according to various propagation environments to be tested.

다양한 이동통신 채널의 모의구현은 시스템 구현 및 검증에 매우 중요한 요소이다. 따라서 본 논문에서는 이동통신 채널을 효율적으로 모의할수 있는 방법을 제안하였다. 새롭게 제안된 방법은 주어진 도플러 스펙트럼 모델로부터 협대역 이동통신 채널의 발생을 가능하게 함으로서 신호대 잡음비, 직접 및 간접 전파경로, 신호전력등의 다양한 전파환경을 고려한 채널의 구현이 가능하다.
