Abstract

In this paper, we derive the outage probability of cellular mobile system with STTB(Space Time Transmitter Diversity) scheme where the received radio signals and interferers experience Rayleigh fading and AWGN. The new probability density function of L independent identically distributed interferers is derived using Laplace transforms. We express the probability of outage as a function of the average-signal to average-interference power ratio and the signal to noise ratio. In addition, the frequency reuse distance which is one of the key parameters in the design of cellular systems is analyzed.

본 논문에서는 레일레이 페이딩과 AWGN 환경에서 STTD(Space Time Transmitter Diversity)기법을 적용한 시스템에서 오수신확률을 유도한다. 라플라스 변환을 이용하여 L개의 독립적이고 동일분포의 다중간섭신호에 대한 새로운 확률밀도함수를 유도하고, 신호대 간섭성분신호의 평균전력의 비와 신호대 잡음의 비로 오수신확률을 나타낸다. 또한 셀룰러 시스템에서 중요한 설계 요소인 주파수 재사용거리에 대하여도 분석한다.
