The Research And Simulation Of Co-existence Interference Of LTE System

Interference in mobile communication systems has been an importeant research topic aspect. There are many kind of interferences,such as spurious interference,obstruction interference,inter-modulation interference and so on.This Paper focuses on the Monte Carlo simulation method for the system co-existence by building the simulation Platform on which the users is moving, and the interferences between the two systems were studied in detail.This article deseribes the system model of adjacent-channel interference Power ratio(ACIR), interference model and evaluation criterions.Three different offset conditions are considered, due to the adjacent channel interference between systems, the capacity loss and throughput loss performance in uplink and downlink are simulated, and a rational analysis and Interpretation is given.Then in this paper,on the basis of the wireless channel propagation prediction models,a module is developed to calculate the field level on the cognitive network.,and udate the network model module.
