A Study on Interference Analysis of PCS BS affecting to IMT-2000 FDD BS, depending on Service Environments

서비스 환경에 따른 PCS기지국에서 IMT-2000 FDD 기지국으로의 간섭분석 연구

In this paper, an interference analyzer for communication and/or broadcasting services is developed and presented based on Monte Carlo technique, which is now under study in the International Telecommunication Union(ITU). Monte Carlo technology is a statistical approach which functions by considering many trials. For each simulation trial, a scenario is built up using a number of different random variables, such as signal and interference strengths, transmitting and receiving antenna heights, antenna gains, etc.. Furthermore, this paper shows and application example of the analyzer to examine interference influence of the PCS(IS-95) base stations affecting to the IMT-2000 FDD base station, depending on serveral service environments like rural, suburban, and urban areas. The wave propagation model used in this simulation is the modified Hata model, which is known to the suitable to Korean environments.
