Modeling the impacts of interference from a satellite ground station on a personal communication system (PCS)

Abstract

In this paper, the impacts of interference f.om a satellite grorind station on a personal comniunication system (PCS) are modeled. A semi-onalylical model is ,first developed to predict the BER perforniance of a ppical PCS base station receiver in the presence of interference ,foni a satellite ground station. The model takes into account the relative transmitted power, waveform structures, antenna patterns, relative geometqi, and traffic patterns for both the PCS and satellite ground station systems. I n order to assess the accuracy of the semi-analytical model, a simulation model is developed, which more accurate[v describes the PCS base-station receiver. Simulations are run ,for a small set of' conditions and results show that the predictioiis of the simulation and semi-ana!vtical models are in close agreemenl.

“…We have conducted a survey of RFI analysis tools and found that, currently; there are many RFI analysis tools available to analyze the impacts of RFI on SATOPS systems [Refs. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Most of RFI tools do not consider the Time Factor (TF) when calculate Bit or Carrier SNR 3 degradation due to interferences.…”
